Error dns host not found Rostelecom television. What does DNS error mean? A temporary DNS error has occurred

Needless to say, many who like to use the Internet quite often encounter a situation in which, when trying to access some resource, the system displays a message stating that the DNS server is not responding. What to do in this case? As an example, consider the operating system of the Windows family. It is worth noting that most often such problems arise in this family of operating systems. Before we move on to correcting this situation, it is necessary to consider several theoretical issues. What is a DNS server and why is it needed?

What is a DNS server?

To put it simply and in clear language, then the DNS server is a means of convenient and correct redirection of requests from an IP address to a domain. It turns out that when visiting any page on the Internet, the user finds himself on the server not by entering some combination of numbers, but by entering the address in Latin characters. This is the main purpose of servers of this type. They are a kind of query interpreters. But what to do when the DNS server doesn't respond? What should I do? Typically 8th and 10th versions operating system Windows does not offer automated tools to correct this situation. However, you can still try to do something.

The DNS server is not responding: what to do?

What could be the problem? First of all, you need to pay attention to the fact that the problem in which the DNS server does not respond may not depend on the settings of the user’s computer. If such a situation is observed, then it may be associated with problems that have arisen on the provider’s side. First you need to call your provider and clarify the situation. However, there are cases when users accidentally or unknowingly change connection parameters on their own. Also, some programs that require Internet access to work correctly can sometimes change their configuration randomly. The same applies to some types of malicious objects. You can try scanning with an antivirus program or even rolling back the system to a previous state when everything was functioning normally. Practice shows that there is little hope for a positive effect in this case, although in some cases it works.

DNS server does not respond: diagnostics using OS tools

First of all, to check the functionality of the connection, you should pay attention to the built-in tools of the Windows operating system. There is a connection icon in the system tray. If you right-click on it, a menu will appear in which you can select the troubleshooting section. The “master” will perform a check in several steps, constantly checking whether the problem has been resolved. Such a check, as a rule, does not bring results. For this reason, you need to act independently.

Checking DNS Client Activity

One of possible reasons for which the DNS server is not responding is a DNS client condition. We will need to check it. To do this, you need to go to the administration section by right-clicking on your computer. You can also use the services.msc command to directly access the services section. Here you need to find a component such as a DNS client. By right-clicking the mouse you can call up a menu with a properties line. Here you should pay attention to the installed startup type. Must be set to automatic. If something else is set in the parameters, you just need to change it, and then reboot the system. To get to the properties of a service, you can simply double-click on its name.

Alternative configuration

Let's consider another option in which a situation arises when the DNS server does not respond. For example, the Rostelecom provider offers its own parameters and values to configure access. However, most providers use a system automatic assignment DNS server addresses, IP addresses and setting other parameters. For this reason, when entering the TCP/IPv4 protocol properties section, the user will not see any numbers there. If, however, it is provided manual settings, but the server does not respond, then you can use other parameters. So, for example, to use the Google DNS server, you can enter the combination 8888 for your preferred DNS, and use 8844 as an alternative using the same input scheme. In most cases, a system reboot is not required for the settings to take effect. It is worth noting that in some cases it is necessary to disable the use of the IPv6 protocol. However, such situations are very rare. You can also try resetting the server. For this purpose, a restart and configuration update must be performed. After this, in the command line launched as an administrator, you should write four commands in sequence: ipconfig/flushdns; ipconfig/registerdns; ipconfig/release; ipconfig/renew.

What other problems might arise?

Basically, that's it for the DNS server not responding problem. It should already be clear what should be done to correct this situation. As for other possible causes of failures, this problem is mostly associated with social networks, which are simply blocked in offices for workers. Sometimes there are problems with modems. Usually just rebooting them is enough. Blocking access to sites with prohibited or questionable content can occur at the firewall or antivirus level. In this case, you need to check the settings. You can bypass system security by using even the simplest anonymous proxy servers. You may also need to reinstall the drivers for your network adapter. As you can see for yourself, there are quite a lot of options.

When the DNS server does not respond, it’s a shame not to know what to do. After all, all the equipment is in good order, there are funds on the balance sheet. But there is no Internet itself due to a banal error in the settings. At the same time, you cannot complain about a breakdown of your laptop or computer, the modem is in perfect order and the provider itself has no problems. But don’t worry, the settings change within a minute and are updated almost instantly. This will be discussed below.

Why are DNS servers needed?

Before moving on to the problem, you need to understand what DNS servers are. By accessing any page located on the network, you gain access to a specific section of the remote server. This directory stores files that the browser interprets and provides information to you in the form of an information page. Each server has its own IP address, which is used to gain access. This practice was convenient when the Internet was a network of several dozen servers. The set of numbers was ideal for scientists accustomed to strict consistency and hierarchy of data. But once the Internet moved beyond the laboratory and became a public entertainment network, there was a need for some other way to identify sites. In order to meet the growing demands of the audience, domains consisting of Latin characters were introduced. Several years ago, their Cyrillic counterparts appeared for visitors from the CIS.

In this video, Roman Kolenov will tell you in simple and accessible language about the operation of DNS servers:

DNS servers exist to correctly redirect from IP to domains.

What problems might arise?

Who most often has problems with servers? Most susceptible to it are modem owners who do not want or cannot switch to the connection option using network cable. In the last few years, such a failure has become very common among providers from Belarus. If you are not using a wireless connection, this problem can only occur if you changed something in the Internet settings yourself. Or as a consequence of the system being affected by a virus or other malicious software. Then first of all check the activity of your firewall and the activity of your antivirus. Have both programs been disabled for a long time without your knowledge? A reason to worry about your network security. Often the problem occurs with a factory modem that the user decided to configure himself. Missing several points in the instructions or inconsistently performing moves leads to the appearance of such an unpleasant notification.

DNS server is not responding, how to fix it?

What can we do without having access to the network:

Reboot modem. The simplest and effective method, just reboot the device. Helps with eliminating most minor troubles if a problem arose during use. After a reboot, the equipment returns to the original parameters that were at the time of startup.
Check, is it specified correctly? addressDNS in settings. To do this, we need “Internet Protocol v4”, which can be found in the properties of “connections via local network" You can find out the required address from your provider; it must be indicated in the documents issued to you.
Update your drivers to the network card. This manipulation helps solve the problem if the previous driver did not work correctly.
Check again antivirus settings andfirewall. Some systems block network access via wireless networks or specific IPs. Go to settings and make sure everything is in order.

Device or resource DNS server is not responding

All these methods are designed to assume that the provider does not have any problems, and the problem lies in your lost settings or a faulty network card. But sometimes things may be different. Due to overload or purely technical problems, the operator does not have enough capacity, and some of its DNS servers do not work. No amount of “dancing with a tambourine” will help you in such a situation, because the problem was not created by you.

In this case, there are two generally accepted solutions. If you do not have an urgent need to gain access in the next few minutes, simply notify the operator about the current situation and demand the fastest possible solution. But you understand perfectly well that any malfunction requires a certain time to eliminate it. The servers will start working in a few hours, your time will be wasted. If deadlines are running out, it’s not finished important work or you urgently need to contact someone - the proposed option is not suitable. If you have a DNS client service running, you can use Google's DNS. Most often, the user makes the mistake of changing the server settings to connect using a network cable, leaving the data for wireless connections the same. If you are afraid of confusion, change the parameters in both fields; this will not reduce the performance of your laptop or computer.

What if it's not a malfunction?

Public access points and workplaces often block access to certain resources. The list of “undesirable” sites includes:

Social media.
Online cinemas.
Torrents.
Resources with prohibited content.

In this case, you can also correct the situation in two ways. Either talk to the network administrator and ask to remove the restriction, or use anonymity tools. Most of the restrictions help you bypass proxy servers. Dozens of websites and browser extensions are now available, thanks to which even a beginner can understand the issue. More advanced users can use the TOR or i2p browser. For visiting social networks these last two options will not work.

When the DNS server does not respond, not all experienced network users know what to do. It is enough to call the provider at the main office and ask him to quickly resolve the problem. Even if she is on your side, the employees will explain what needs to be done and in what order.

Video lesson

It is impossible to imagine our existence without access to sources of information that the Internet provides. DNS servers are the connecting link of a network of computers. Unfortunately, sometimes errors occur in their work. In these cases, access to the Internet is limited or non-existent. Therefore, every user will benefit from basic knowledge on the topic.

What is a DNS server and why errors may occur

If you explain in simple words, we can call the DNS server the address book of the Internet. Each computer connected to the network receives an IP address in the form of a digital value similar to this - 127.0.0.1. Each published website has a domain name - http://hostus.ru. The main task of a DNS server is to convert (translate) a domain name into IP addresses and the reverse process.

Video: explanation of how a DNS server works

Unfortunately, sometimes there are glitches in the chain. Errors occur. There can be quite a few reasons, let’s look at the most common ones:

no internet connection;
incorrect router or modem settings;
incorrect firewall settings;
The network card driver is critically outdated;
computer infection with a virus;
work on the provider's DNS server;
software errors on the site.

Troubleshooting should begin by checking the simplest settings, and only if unsuccessful, proceed carefully to more complex actions.

Common DNS errors

Let's look at the most common errors that are usually easy to fix on your own. Typically the fix doesn't take too long.

The DNS server is not responding, the DNS server address cannot be found

Probably the most common problem.

This is what the error message looks like in the browser window

When an error appears as a result of an attempt to log in to a certain resource, and the others work fine, most likely problems arise on the site. There is no way to fix anything in this case. Be patient, maybe after a while everything will work as normal.

DNS errors may appear due to malfunctions in the router. And also the Internet provider may be to blame for their occurrence. Reboot or turn off the router for a while, perhaps this action will clear the error. There are no changes - try connecting the Internet cable to your PC or laptop directly, bypassing the router. If the action does not help, call your provider, the problem is probably on their side.

When all devices are working normally, but the error occurs on one computer, most likely it is due to the malfunction of the device itself. Consideration of such an error is worthy of a separate publication.

Windows can't contact the device or resource

Let's consider this option - the main applications continue to work, the Internet is connected, but the resource we need is unavailable, when accessing the site a message appears on the screen: “Cannot find DNS address server."

The browser displays an error message

To find out the causes of the error, run network diagnostics:

Failure message when the system tries to connect to the DNS server

This error can have different causes. Methods for solving the problem are selected accordingly:

incorrect work antivirus program- try to disable it temporarily or install another one;
DNS may be faulty - Windows client - open Control Panel, Administrative Tools, Services tab and restart the DNS client service, turn off and restart the computer.

If all of the above steps are unsuccessful, try resetting the DNS cache. Press Win+R, in the window that appears, type “ipconfig/flushdns”, start the process.

The DNS cache is cleared by running the command “ipconfig/flushdns”

After completing the steps, everything should work fine.

No access to DNS server

Users often encounter a situation where all devices are working normally, payment has been made to the provider, but there is no access to the World Wide Web. The cause of the error is incorrect Internet access settings. Everything can be fixed on your own.

To resolve the error, do the following:

In the "Start" menu, go to "Control Panel", item - "Administration", select section - "Services".
Select the services item in the Administration section, Windows Control Panel
Find the line “DNS client”, there should be an inscription: “Working”.
When DNS is running, the DNSP client line always contains the entry “Working”
If the line is empty, move the mouse cursor, press the left button, call context menu by clicking Properties.
Next, in the “Startup type” column, specify: “Automatic”.
On the tab you must specify the startup type: “Automatic”

Click "Apply" and "OK".

In a situation where the service is running but there is no network access, the following actions should help:

Log in to the control panel, open the tab there: “Network and Sharing Center” shared access».
Open the Network and Sharing Center tab in the Windows Control Panel window
In the “Changing adapter settings” section, call up the network connection context menu.
Select "Change adapter settings" under "Network and Sharing Center"
In the tab that appears, click on the “Properties” line.
On the “Local Area Connection” tab, select “Properties”
In a new tab, highlight the line “Internet Protocol 4 (TCP/IP 4)” and click “Properties” again.
Highlight “Internet Protocol 4 (TCP/IP 4)”, click “Properties”
In the next window that appears, check the box “Use the following DNS server addresses.”
Set the server IP address manually
In the “Preferred DNS server” line, type “8. 8. 8. 8.”
The line “Alternative DNS server” should be filled in like this “8. 8. 4. 4".
Click "OK".

If everything is done correctly, but there is no positive result, there is a high probability Windows errors. Try performing a system restore to the last point when everything was working correctly. To do this, go to the Start menu, Control Panel, Recovery. Select a restore point, run the procedure, restart your computer.

If the browser continues to generate an error, the following actions are possible to solve the problem:

Such manipulations will help identify the application that interferes with the normal loading of sites.

Another cause of the error may be outdated network adapter drivers. Find its model. On the manufacturer's website, download new programs and install.

If none of the above helped, then your computer is attacked by a virus, do the following:

Download the healing utility Dr. Web CureIt or another with similar functionality.
Perform a full scan of your computer.
Remove infected files.

There is one more error worth noting. Sometimes when you try to access the Internet, you can see the message: “Unable to resolve the DNS server address.” Most often, the error is associated with repair work on the DNS service that provides network access services. Check your Internet connection by connecting another computer or laptop to it. If the error appears on all devices, contact your provider. In the case where the error is specific to one device, your actions are similar to correcting the “no access to DNS server” error. Your system appears to be sending incorrect queries to the DNS server.

Software errors

These include DNS failures caused by software errors in servers and individual sites.

A temporary DNS error has occurred

This message is caused by DNS problems in Exchange 2013. Microsoft Exchange Server is a software product for messaging and collaboration. It is not entirely clear what “Temporary server error” means. Please try again later. PRX 3". At the end there is also PRX 1, PRX 3, PRX 7. Unfortunately, there is no documentation.
Known different ways problem solving. If your computer has built-in LAN card, and an additional external one is installed, disable the one that is not used. To do this you need to do the following:

start the PC or reboot if the computer is turned on and when starting the BIOS, press the F12 or Del key;
To enter the settings, use the F1, F10 and other keys - if you don’t know which one to choose, read the text “Press... to enter Setup”, where the desired combination will be written;
in the parameters, open the section with the word Integrated, where you will need the line On Board LAN or something similar;
change the status of the line to Disabled to deactivate it;
Don't forget to use the Save and Exit button to save your changes.

BIOS panel, through which changes are made to the hardware configuration

Be careful, if you do not have confidence in your actions, do not experiment with the computer BIOS, it is better to invite a specialist.

When there is only one network card or disabling the second one does not help clear the error, try the following actions:

Failed to resolve DNS domain controller name

A specific error that is rarely encountered by ordinary PC users. Typical for systems included in domain Windows network managed by Active Directory. AD represents a set of processes and services that allows you to centrally manage the local network infrastructure. All computers on the network are united into a common domain. An error occurs when trying to introduce a new server to the domain. The system displays the message “Failed to resolve DNS - domain controller name.”
Try the following:

Couldn't load the page because the site wasn't found in DNS

The error mainly relates to the work of webmasters. When registering a new domain, DNS servers do not know its address. Until information about it appears on the DNS servers, the website, mail, and other elements will not work. The DNS server registered for the domain acts as a “herald”, thanks to which the site address will become known to other servers. First, domain information appears on the hosting DNS. If you are the owner of a website, and when you try to open it, the error “the address for the domain of this website was not found on the DNS server” is displayed, contact your hosting administration.

A similar error may occur when transferring a domain to another hosting. In this case, the domain name of the site is the same, but the IP address changes. To solve the problem, you need to contact your hosting administration.

Other common mistakes

In addition to those already discussed, other problems may arise related to the DNS server.

Table: common DNS errors and how to resolve them

Event ID	Error message	Possible errors and corrective action
408	The DNS server cannot open a socket for the IP address. Make sure this is one of the valid server computer addresses.	If the IP address is valid, check to see if another device or program is trying to use the DNS service port (53).
413	The DNS server will send queries to other DNS servers on a port other than the default (TCP port 53).	This issue occurs on computers with multiple network adapters(when the DNS server is configured to use only a portion of the available IP addresses). In addition, it may turn out that the answers remote servers DNS attempts to use a port that the local DNS server is not configured to use, causing problems in replicating zone data across WAN connections (through firewalls). To ensure that the configured port is used for all connections, change the configuration of the IP interfaces so that one of the following conditions is true: All IP addresses are used. Only one of the IP addresses is used.
414	The server computer does not have a primary DNS suffix configured.	For example, the server name is dns 1 instead of dns1.company.net. This configuration may result in incorrect or failed calls. To fix this issue, connect the DNS server to your domain or provide a fully qualified DNS name that is appropriate for your workgroup.
708	The DNS server did not find any primary or secondary zones. The server starts in cache-only mode and is not authoritative for any of the zones.	If creating only a caching DNS server was the main goal, then nothing needs to be done. Otherwise, this message implies that you need to configure zones on the server.
3150	The DNS server wrote the new version of the zone "zonename" to the file filename. New version can be viewed by going to the tab.	This event occurs when the DNS server is configured to act as a root server. If this is not the desired result, you will need to remove the root zone (.) to prevent these messages from appearing.
6527	The zone "zonename" expired before the zone was successfully transferred or updated from the primary server that is the source of the zone. The zone has been disabled.	Secondary DNS server lost network connection with the primary server, so replication cannot be performed. Solve the network problem. On the secondary server, delete and recreate the zone with the correct IP address for the same or a new primary server. The primary server has an incorrect zone configuration in the SOA record. Fix this by using one of the suggested actions. Make sure that the Refresh Intervals value is less than the Expires After value. Decrease the Retry Interval value. Increase the Expires After value. Add the secondary server to the Notify List.

At first glance, the problems listed in the article seem complex and almost unsolvable. But having carefully understood the topic, everything can be corrected on your own. This will require patience and time. But the main thing you need is desire.

Users, when opening a website in a browser instead of the usual page, sometimes encounter a problem with error code 105 and a message that the required DNS server was not found. This is due to the unavailability of the Domain Name System. Let's figure out how to restore the page's functionality and avoid errors in the future.

What is DNS: an abbreviation from English. “Domain Name System” is a domain name system, which, in accordance with the address of the requested site, is provided with a digital or IP address. That is, when a user enters www.yandex.ru, the DNS server, using its internal routing table, finds a correspondence between the literal value and the digital value, providing the answer to the user in the form of a website. If unsuccessful, the site will inform the user that “DNS server not found.”

Another name for such an error, often encountered when loading a site, is “net: err not name resolved.” The message means that Windows system is not able to convert the digital value of the required site into the required format. Moreover, the failure occurs only on certain browsers, while others open and work.

Possible causes of DNS errors

The message “DNS server address not found” means the following:

The Domain Name System did not find a match between the alphabetic name and the numeric name and returns a message to the user with error code 105.
The router is not configured correctly: incorrect DNS servers were specified when configuring the router. As a result, the user's request is sent to nowhere.
Your local provider is having problems with their DNS servers.
The antivirus program is blocking access to the site.

The problem is on the end device, for example the user's home computer. The DNS cache is full or the tcp/ip protocol settings are lost.

Solving the problem at the computer level

The simplest solution to the problem is to check home computer. Open the required site with another browser. It is possible that the program uses incorrect settings or has unnecessary extensions installed, which is why web pages do not open.

The next step is to clear the service's DNS cache. Call up the dialog box by pressing the “Win” + “R” keys and enter the “ipconfig /flushdns” command in the line.

After completing the operation, check your Internet access.

Checking the DNS Client service

Right-click on the “My Computer” icon and select “Manage.”

A window will open with a list of available utilities.

Click on “Services and Applications”, then “Services” and pay attention to the window that opens on the right.

Among the services, find “DNS Client” and right-click on it. A context menu will open. Select "Property".

Be sure to check the “Startup Type” field, the presence of the “Automatic” status, the “Status” field, and the “Running” status.

Close the current window by clicking “OK”, select the “DNS Client” service and the “Restart” option.

Close all windows and restart your computer.

DNS server address changes

If the message that the server's DNS address could not be converted does not disappear, you should change the Domain Name System in the network adapter settings.

Most providers offer a local Domain Name System server. It is recommended to take a memo from your Internet service provider and check it with the data indicated in the lines.

After that, close all windows and check whether a message is displayed stating that the DNS server could not be found in the browser.

Alternative DNS servers

It is not uncommon for a local service provider to experience a technical failure, resulting in the end user being unable to connect to the World Wide Web. In these cases, alternative Domain name System values are used. The secondary DNS line usually contains public values. The most famous public Domain Name System servers are provided by Google, Yandex, and OpenDNS. A complete list of public addresses in the Russian Federation is located on the website: https://public-dns.info/nameserver/ru.html If other countries are needed, a choice is provided for any country.

Alternative configurations are convenient because they are always available. This checks the availability of local provider addresses.

Setting up DNS from Google

If, when you try to load the page, a message still pops up informing you that the required dns address of the server could not be found, you need to change the Primary name address of the server from the provider to the address from Google. Everything is in the public domain and was specially developed by Google for stable and continuous operation of the Internet.

To do this, you need to open the properties of the “IP version 4 (TCP/IPv4)” protocol, as indicated above in the paragraph “Changing the DNS server address”, and follow the instructions.

Features of Google Public DNS

The peculiarity of Google's Domain Name System servers is that they are always available and work without interruption. Advantages include continuous scanning mode global network for changes DNS servers in the world. But there is also a drawback: due to the large geographical distance, it seems as if the Internet is “slow.” In fact, there is a delay in data transmission.

The local provider's DNS server database is updated less frequently than Google's. Accordingly, using publicly available data, the user receives constantly updated addresses.

Antivirus malfunction

The antivirus program can block some Domain Name System servers. The user observes a situation where other unblocked sites open, and the desired one displays error message 105: “unable to resolve the server’s DNS address.”

Let's look at the reason that provokes such a situation.

Any antivirus includes a component called a firewall. “Firewall” from English. "fire" - fire, "wall" - wall. Literally translated as “wall of fire”, it is essentially a play on words. Another name is a firewall or firewall.

Its functions can be compared to a water filter: all the “garbage” remains behind the firewall. “Junk” refers to various viruses, keyboard spyware, annoying advertising and other malware. In some cases, the firewall blocks access to sites, considering them “malicious”.

Before checking your antivirus program settings, you must boot your computer into safe mode. To do this call command line, by pressing the “win” + “R” keys, enter msconfig, then enter.

Go to the "Boot" tab, activate safe mode by selecting the "Network" boot option. Save the changes by clicking the “Ok” button. After completing all the steps, reboot the workstation, and it will automatically load into safe mode.

In this mode, launch the browser and go to any website. If everything works stably, then the problem is in the antivirus. There are two options here: either complete the settings given below, or install it again.

First option. It is necessary to disable the component in the antivirus settings network protection. Using Avast antivirus as an example, it looks like this:

double-click the left mouse button on Avast to open the main antivirus window;
then select “Protection”, “Main protection components”;
disable the firewall by clicking on the green bar;
10 minutes is enough to check the functionality of the World Wide Web;
a warning message immediately appears about the vulnerability of the computer in the event of various network attacks;
close the antivirus and check whether the error blocking the desired site has disappeared.

Checking the router

If you still get the "dns cannot be found" message when you try to open a web page, the next step is to check your router settings. First you need to go to the main settings of the router. Most users use Wi-Fi routers at home to create wireless network in a residential area. This helps to use the Internet both on workstations and other equipment equipped with a Wi-Fi module.

Address network device and authorization data is usually indicated on the router itself on a special label. Open a browser and enter the IP address specified on the router, followed by the username and password. Here, as an example, we consider one of the TP-Link routers:

Having accessed the router settings, go to the “Network” menu.

Check the “Use the following DNS server addresses” option and manually specify the required DNS server addresses. It is recommended that in the line “Preferred DNS server” - in English “Primary Domain Name System server” - indicate the address issued by the local provider, and in the second line - a public address, for example, “8.8.8.8”.

Left-click to activate reboot of the network device. After this, check the functionality of the connection when connected to the Internet.

Solving a problem on your phone

Android phones also sometimes have a glitch that blocks the opening of the site. This means that when connecting the communicator to a Wi-Fi network, it is not possible to convert the name dns server address. Below is a guide to correcting this error. The Lenovo P2 model is taken as an example. Android based 7.

go to your phone settings by swiping from the top;
select the “WLAN” menu item, indicated by the Wi-Fi symbol;
then select the connected one Wi-Fi network– where the status is “Connected”, holding your finger on the name of the network. Next is the “Change” property;

select the “Advanced settings” item, submenu “IP Settings - DHCP”;
switch to user settings mode;
Now you have access to change DNS servers. If the addresses of a local provider are found, we change them to publicly available ones, for example, from Google;

save changes made, reconnect Wi-Fi on your phone. After performing all the above steps on the phone, the error message disappears.

Solving the problem on the TV

If an error occurs with the message “Err name not resolved” on TVs with a built-in Wi-Fi module, you must do the following.

open the TV settings menu, then select “Wireless.” (are common)";
go to the “IP Settings” menu, set the mode for obtaining IP to “Manual”;
specify the Domain Name System of the server from the public list, for example, 8.8.8.8. After saving the settings, download again.

As a rule, each TV manufacturer prescribes its own domain name system, but they can be unstable. This results in the alert “Unable to resolve the current DNS server address” appearing.

Prevention methods

To prevent the “error 105” problem, it is recommended to use the following preventative methods:

Run an antivirus scan for malware once a week.
On the router, as the primary DNS server, specify the address of the local provider that provides the user with Internet access. And the secondary address is from English. “Secondary Name DNS Server” is one of the list of public DNS Addresses.

Conclusion

The article discussed various ways solutions to the problem known as error 105 on various devices indicating the problem message. It occurs both on computers and on phones or TVs. The methods listed above work equally on Windows 8, Windows 10.

It’s unpleasant to encounter problems with your Internet connection, but sometimes it can’t be avoided. One common failure occurs when the server's DNS address cannot be found. Let's look at what it is this problem, and how to eliminate it.

Description of the error

DNS (Domain Name System) is a bridge between human and computer perception in the sense that it allows the conversion of a user-friendly alphabetic domain name (what is written in address bar of the form “www.google.com”) into a machine-friendly numeric equivalent (node IP address).

A DNS error (aka "Error 105", ERR_NAME_NOT_RESOLVED) occurs when the web browser is unable to perform the translation, then the site will not be accessible.

Troubleshooting steps

First of all, you need to find out at what level the failure occurred.

Possible options with signs:

problems at the site level— an error is issued when loading only one site, others open;
problems at the provider level— not a single device in this local network loads pages, there is an error everywhere, when the same device is connected to another network, the connection works correctly;
router level failure- the signs are the same as in the previous case;
computer level error— Internet problems are not detected on other devices connected to the same network.

Solving the problem at the PC level

First of all, make sure that the DNS service is running and restart it:

Did not help? The next step is to clear the DNS cache.

Changing the DNS server address

Alternative DNS server

If the previous steps did not lead to the desired result, you can connect to another DNS server. In this case, DNS requests will be addressed instead of the provider's server to the one you specify. This method can also be used to bypass restrictions that ISPs may impose on websites.

Please note the following point: changing the DNS server address to one that is publicly available puts your data at risk. For security purposes, use servers with a good reputation, for example, Google Public DNS, OpenDNS, Yandex.DNS.

Setting up Google DNS

Login to " Network connections", select the connection to your network, TCP/IPv4. Check "Use the following DNS server addresses" and enter Google IP addresses: 8.8.8.8 and 8.8.4.4.

The addresses of other servers are written in the same way.

Features of Google Public DNS

When using Google servers, request processing may be slower than when working with local servers providers. The reason for this phenomenon is the remote geographical location, due to which the request needs to travel a greater distance.

To counteract the possible delay, Google uses its own technologies for scanning the Internet and caching information, which benefits performance.

A possible cause of an error when loading a specific site is that it has moved to another IP address while the information on the local DNS server has not yet been updated. Because Google crawls the web constantly, the information on its servers is more up-to-date, and connecting to them may solve the problem.

Antivirus malfunction

Problems with the Internet connection can be caused by a faulty antivirus. To find out if this is your case, put your computer in safe mode.

For Windows 10, switching is done in the following way:

In safe mode, the antivirus software does not turn on; if sites load normally, the antivirus is the source of the problem, you need to reinstall it.

Checking the router

Problems at the level Wi-Fi router the “symptoms” are no different from a failure at the provider level, but there is a way to distinguish them.

Disconnect the Ethernet cable from the router and plug it into the computer connector.

This will establish an Ethernet connection. If, when connecting directly, the problems with the Internet are resolved, the problem is with the router, and it needs to be rebooted.

To reboot, turn off the router, wait 10-30 seconds and turn it on again.

In other cases

If you have tried all the above methods and the problem still persists (no page loads), contact your ISP.

If one specific site produces an error, the cause of the failure is on the side of its owners or hosting. In this case, you will have to wait. Sometimes it can be informative search query like “why is the site xxx.yyy.com not working”, which may shed light on the source of the problems.
