How to Solve The Error “ERR_NAME_NOT_RESOLVED”

“ERR_NAME_NOT_RESOLVED” is a common error you might have come across while accessing websites. When this error pops up on your screen, it restricts your access to the website and only gives you the option to reload the page.


Let’s look into the causes of this error and ways to fix this error in six simple ways.


What causes this error?

In order to resolve this error, we need to understand where this error generates from. The top common causes of “ERR_NAME_NOT_RESOLVED” are listed below:

  1. DNS (Domain Name Server) Address

When the requested URL has a domain or subdomain that is missing or does not exist, then the browser will return an “ERR_NAME_NOT_RESOLVED.” If the necessary DNS records do not exist in the Cloudfare configuration, like the root domain and subdomain, then it will cause this error.


  1. IP Address

When the IP address that’s searched for does not connect to a valid DNS record, then you’ll get an “ERR_NAME_NOT_RESOLVED” on your Android, Chrome, and Windows application.


  1. Firewall

When your Firewall or antivirus is blocking your connection, then the connection will not be established. Due to this issue, an “ERR_NAME_NOT_RESOLVED” will pop up on your web browser. This generally occurs when you have updated the software.


  1. Proxy Server

If you have changed the proxy settings in your browser at some point in time and did not change them back, then this might be your potential cause. You can easily check your proxy settings to confirm this.


Best Ways to resolve this error


FIX 1: Switching your DNS address

A simple way to fix the “ERR_NAME_NOT_RESOLVED” issue in Chrome is by switching your existing DNS to an open Google DNS.

You have to go to the start menu and simply press the “Windows” key and the “R” key together. A dialogue box will open. Type “control” in it. This will open the control panel.

Here are the steps to follow:

In the control panel, go to “Network and Sharing Center” and then select Change Adapter Settings.

Next, right-click on “Properties” and go to the “Networking” tab.

Next, choose “Internet Protocol Version 4 (TCP/IPv4).”

Again, go to “Properties,” then the General tab, and enter the following DNS server addresses.

Switching your DNS address

In the “Preferred DNS Server,” type “” and in “Alternate DNS Server” type “” Press OK.

Once this whole process is completed, check the website you were trying to access. In most cases, that was the cause of the error and by changing the DNS server, the problem is resolved.

You can also try to connect to a different network, and if that option in unavailable, you can use a VPN service temporarily.

If the error is fixed and the webpage loads, then it is possibile that the website you are visiting is blocked by your ISP.


FIX 2: Disabling Firewall

Your antivirus or Firewall may be blocking you from accessing certain websites or even the Internet in general. So you can check your Firewall for any issues or try to disable it for some time to access the websites easily.

You can temporarily disable your anti-malware and then check for the error. If the error persists, then it is not caused by the Firewall, and if the error is removed, it has something to do with your Firewall.

Disabling Firewall

If the error occurs due to your anti-malware, then you should change your anti-malware or reinstall the correct antivirus package in your system.


FIX 3: Delete browser cookies

When you browse through any website, small packets of information get stored on your computer, which are known as cookies. These cookies prevent you from reaching other websites, blocking your DNS address.

You will just have to delete your browser cookies in the Settings. Once you go to Settings, go to Advanced -> Clear Browsing Data -> Cookies and other sites and Plugin Data -> Clear browsing data.

Once your browsing history is cleared, you can clear the host cache on chrome://net-internals/#dns. Then you should try to access your website again and see if the error has vanished.


FIX 4: Resetting your IP address

Resetting your network settings is a simple and effective way of resolving the error. You just have to run the command prompt and execute “ipconfig” and “netsh” commands.

Go to Start -> Type “cmd” -> Enter -> Right-click on Command Prompt -> Run as administrator -> Yes.

After this process, type the following commands:

  • ipconfig /flushdns
  • ipconfig /renew
  • ipconfig /registerdns

Resetting your IP address

After each command, you have to press Enter and wait for the whole process to complete before typing the next command.

After this process is over, check for the “ERR_NAME_NOT_RESOLVED” error in Chrome and see if it is fixed or not.


FIX 5: Re-plugging your router

Re-plugging your router can also help in resolving this error. Switch off your router and plug it back in after a few minutes.

After doing so, check for the error in your browser and see if it is resolved.


FIX 6: Disabling prediction service in Google Chrome

The prediction service can also hamper your DNS address, resulting in the “ERR_NAME_NOT_RESOLVED” error displaying in your browser, whether it is Android, Windows or iOS.

Go to Settings -> Advanced settings -> Privacy settings -> Use a prediction service to load pages more quickly -> Turn it off.

Reload the page you searched for and see if the error is resolved.

Disabling prediction service in Google Chrome

We hope that these tips will help you in resolving the “ERR_NAME_NOT_RESOLVED” error effectively on Chrome, Android, iOS, and Windows.

If the issues still persist, then you should contact the manufacturer of the router and confirm that there is no hardware problem with your device.
