Clear Browsing Data

Browsing data consists of a records of Web pages that you have visited in your past browsing sessions, and typically includes the name of the Website as well as its corresponding URL. Other private data components such as cache, cookies, saved passwords, etc., are also saved during your browsing session. All this stored data can either slow down your browser or even prevent you from accessing websites and cause the "ERR_NAME_NOT_RESOLVED" error. To clear Google Chrome's browsing data cache, click the three dots in the top-right corner, select "More tools" and click "Clear browsing data...".

clear browsing data step 1

In Clear browsing data window select what data you want to remove from your browsing Google Chrome cache and click "CLEAR DATA" button. Make sure that you select to remove "Cookies and other site data", other options like "Cached images and files" and "Hosted app data" are optional. Restart Google Chrome and see if you are still getting the "ERR_NAME_NOT_RESOLVED" error.

Another thing that might help is to clear Google Chrome Host Cache.

Switch To Google DNS

Google's Public DNS, a free alternative Domain Name System (DNS) service offered to Internet users around the world. The public DNS service and servers are maintained and owned by Google. It functions as a recursive name server providing domain name resolution for any host on the Internet. We recommend to use Google DNS for faster and secure connection and using Google DNS could also fix the "ERR_NAME_NOT_RESOLVED" error. You will have to change the DNS manually, and we are going to show you how.

To change your DNS server to Google's DNS server, go to your Network Connections settings. Right-click the Start menu and select "Network Connections", or go to Settings and click "Network & Internet".

In the Network & Internet settings window, select your connection type (in our case, "Ethernet") on the left pane and then click "Change adapter options" on the right pane.

Right-click on your connection and select "Properties" from the drop-down menu.

Reset Network Settings

To reset network settings you will need to execute several commands using Command Prompt, this method includes entering and executing "ipcofig" and "netsh" commands. Ipconfig is a command-line tool that displays the current configuration of the installed IP stack on a networked computer. Using tool, we can flush and reset the contents of the DNS client resolver cache and renew DHCP configuration. Netsh is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running. Netsh also provides a scripting feature that allows you to run a group of commands in batch mode against a specified computer.

The commands require an elevated Command Prompt opened with administrator privileges. To open elevated Command Prompt, type "command prompt" in Search and right-click on the "Command Prompt" result. Choose "Run as administrator" to run it with administrative privileges. When you select "Run as administrator", a User Account Control prompt will appear asking if you allow the Command Prompt to make changes to your computer. Click "Yes".

reset network settings step 1

Now type these commands and press Enter after each:

ipconfig /release
ipconfig /all
ipconfig /flushdns
ipconfig /renew
netsh int ip set dns
netsh winsock reset

reset network settings step 2

Restart your computer when you are done, launch Google Chrome and see if the "ERR_NAME_NOT_RESOLVED" error still persists.

Temporarily Disable Your Antivirus

It is possible that your antivirus (anti-malware) software is blocking the access to some or all of the websites and that is why you are getting the "ERR_NAME_NOT_RESOLVED" error. To make sure that the installed third-party antivirus software is not the culprit of this error we recommend you to try to temporarily disable it and check if the error still persists. If disabling (or uninstalling) your antivirus actually helps, then we recommend you to switch to another antivirus software or to reinstall the currently installed one. If you are not sure how to disable your antivirus, then read this guide. There you will find instructions on how to disable some of the most popular antivirus programs. Additionally, if you are using any VPN client, then try to disable it. If you are using some firewall, then temporary disable it as well and see if the error still persists.

Disable Prediction Service

This feature allows Chrome to load pages faster when you are accessing them. Prefetching is also know as "prerendering". It means that when enabled, the feature caches pages that are linked on the web page you are currently on. So, next time you open the same web page it will load faster. A downside of this feature is that you will be downloading resources from pages you visited but may never visit again, and this can use more system resources and, in some cases, prevent you from accessing certain websites and cause the "ERR_NAME_NOT_RESOLVED" error. To access this feature, go to "Customise and control" (three dots on the upper-right corner) and then click "Settings".

disable prediction service step 1

When the "Settings" page appears, click "Advanced".

disable prediction service step 2

In the "Privacy and security" section, find "Use a prediction service to load pages more quickly" and disable it by toggling the switch to the "Off" position (the switch should be grayed).

Restart Your Router

Another thing we recommend you to try out is to unplug your modem (or router) from the power plug and leave it unplugged for a couple of minutes. Then plug your router (or modem) in again and wait until it finishes the startup (self test) process. Plug your router or modem into a power source again and see if the "ERR_NAME_NOT_RESOLVED" error gets fixed.

That's it, we hope one of the methods solved the problem and fixed the "ERR_NAME_NOT_RESOLVED" Google Chrome error for you.
