There is an endless number of sites available on the internet. Accessing a web project is as simple as selecting its domain name and opening an internet browser. To represent the numerical IP address of a website, you type its domain name into the address bar of your web browser. This automatic translation is referred to as domain name resolution by DNS (Domain Name Server) servers. In the case of a faulty domain name, you will encounter errors that prevent you from accessing the site. If this happens, Google Chrome displays an error message that reads ” ERR _NAME_NOT_RESOLVED”.

Below you’ll find information about the possible causes of DNS domain name resolution errors. We will also provide you with troubleshooting tips that will help you fix Chrome’s ” ERR _NAME_NOT_RESOLVED” error.

Error message “ERR_NAME_NOT_RESOLVED”: what does it mean?

If you get the error message “ERR_NAME_NOT_RESOLVED”, Chrome is telling you that it could not find an IP address that matches the domain name you entered. Since the IP address is needed to establish a connection with the webserver, you will not be able to access the page if this occurs. Any computer running Chrome (Windows, macOS, or Linux) or any mobile device running Chrome (Android or iOS) will encounter this error. Chrome is not the only browser in which this error occurs; Firefox and Safari can also produce this error. The error message they display when DNS resolves the domain name, however, is different from that of Google Chrome.

The “ERR_NAME_NOT_RESOLVED” error has several possible causes

The failure of DNS domain name resolution can be caused by some factors. DNS server (temporarily) unavailable is one of the most common reasons for the issue. If there is no entry for your desired website in the cache of your operating system or your browser, the DNS will not be able to resolve the domain name. It is also possible that the address entries that have been mentioned can contribute to the error “ERR_NAME_NOT_RESOLVED” in Chrome. An example of this error is when the browser tries to answer a DNS request with a cached address while the IP address has since changed. This error may also be caused by router problems, incorrectly configured internet settings, Chrome’s prediction service for faster page loading, malware, and faulty security software.

Chrome error ERR_NAME_NOT_RESOLVED: How to fix it

There is no universal solution to DNS problems since they can be caused by many different factors. In the following sections, we will discuss the solutions that have the highest chances of working when dealing with Error Name Not Solved errors.

Restart the router

Firstly, you should check the router which connects your device to the internet before you begin fiddling with Chrome settings or your operating system. It is still possible that your internet connection is not working, even if it appears to be. For potential quick and easy solutions to the “ERR_NAME_NOT_RESOLVED” error, you need to restart the network device. Disconnect the power supply by unplugging the power cable for at least 30 seconds to restart the device. Plugin the power cable again and reboot the device.


It will take a while for the router to fully resume operation after being temporarily disconnected from the power supply. By restarting your router, you can test whether the DNS problem has been resolved after the internet/DSL light has turned green.

Delete your browsing data

The default setting in Chrome is to store data on all the websites you have visited in the past. By caching data, pages load faster when reloaded and auto-complete addresses as you type them. However, this function can quickly become a problem, resulting in the “ERR_NAME_NOT_RESOLVED” error when using Android, Windows, etc. Therefore, deleting all browser data may be a solution. Using the three-dot icon, open the Chrome menu and select “More tools”. Click “Clear browsing data”.

In Chrome for Android and iOS, it is not possible to find the “Clear browsing data” option under “More tools”. Click History instead.

The next step is to choose the types of browser data Chrome should delete from the cache. “Browser history” and “Cookies and other site data” are both mandatory. Under “Time range,” make sure you select “All time”, otherwise your most recent browser history will be deleted. Once you’ve selected the “All time” option, click “Clear data”.

Your operating system’s DNS cache should be cleared

Cached web addresses are usually only associated with the browser, the user interface for accessing the internet. However, standard operating systems such as Windows, macOS, and Linux also include browsers that remember DNS entries for previously visited websites. When DNS cache entries for an address are incorrect or out of date, they can cause the same type of error as the browser’s cache, such as the “ERR_NAME_NOT_RESOLVED” error in Chrome. This problem can also be fixed by clearing the cache, which is also known as a DNS flush.

 If you have Windows 10, you can perform a DNS flush with a single command at the command prompt. Click the Start button first. Select “Command Prompt”. Search for it as an alternative. You can clear the DNS cache after you open the command prompt window by entering the following command:

ipconfig /flushdns

A message will appear saying the cache was successfully emptied after a few seconds.

Reset the Winsock catalog

Users of Windows should try the interface and system application Winsock (also known as Windows Sockets) if the “ERR_NAME_NOT_RESOLVED” error was not caused by the browser cache or DNS cache. As a result, Winsock creates entries for each connection established so programs can communicate using TCP/IP. It is possible to resolve connection problems in the Chrome browser by resetting the Winsock catalog since this data can also prevent a website from being accessed. This reset can also be performed from the command prompt window, just like the DNS flush.

Nevertheless, the command must be run as an administrator in this situation, as explained below:

1. Click the Windows icon in the Start menu.

2. Depending on your operating system version, you will find the “Command Prompt” icon under “Accessories” or “Windows System”.

3. Select “Run as administrator” by right-clicking “Command Prompt”.

You can reset the Winsock catalog by entering the following command at the Windows command prompt:

netsh winsock reset

The command will run when you press Enter. The system will then be reset after you restart it.

Change the DNS server

Chrome displays the “ERR_NAME_NOT_RESOLVED” error message if the DNS server is not working, and it is not much you can do to resolve it. DNS address settings can be changed to use IPv4 or IPv6 to switch to a different DNS server. Among the best public DNS servers are Cloud flares. They are available at and, as well as 2606:4700:4700::1111 and 2606:4700:4700::1001.

The following steps will allow you to make these DNS servers, which are designed to be fast and secure, the default option on Windows:

1. Use the Start menu to open the Control Panel.

2. Click on “Network and Sharing Center” (in the icon view).

3. From there, select “Change Adapter Settings”.

4. Select “Properties” by right-clicking on the network adapter that connects you to the internet.

5. Right-click on “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)”.

6. For the preferred and alternate DNS servers, enter the above-mentioned addresses under “Use the following DNS server addresses.”.

7. Click “OK” to save your changes.

Disable Chrome predictions

With the prediction function, Google Chrome provides faster loading times over the long term. To accomplish this, the function automatically collects information about any links on the currently open website to improve the load time for those linked pages if you happen to click on one of them. Nonetheless, this prediction service can cause DNS problems such as the ERR_NAME_NOT_RESOLVED error, so if you disable this function in Chrome, your DNS problem should go away.

Open the Chrome menu, then click the three-dot icon, to turn off the prediction function. Next, click on “Settings”. Click “Show advanced settings” in the following menu. You can preload pages to enhance browsing and search performance by moving the slider to the left for “Privacy and security”.


Disable security software temporarily

On Android, Windows, or any other operating system, the Chrome “ERR_NAME_NOT_RESOLVED” error can also be caused by security software. The browser will respond with an error if the website cannot be accessed because antivirus software or a firewall is blocking access. If you temporarily disable the applications you are using, you will be able to determine if they are causing issues. Upon resolving the domain name, you will be able to determine which domain caused the error. The publisher of the faulty software can be contacted or a suitable replacement software can be found.

Check for malware

As is the case with many computer errors, malicious software on your system may be to blame for the “ERR_NAME_NOT_RESOLVED” error. Malware, for example, can change your DNS server configuration, change your browser history, or prevent the domain name from being resolved in some other way. Therefore, if the solutions described above do not work, it is important to check your system for possible malware infection. You can either scan with your security software or with the Microsoft Malicious Software Removal Tool (MSRT). Users of Windows must be in a position to use the MSRT, who can do so only with administrator rights.
