How to Fix the “your DNS server might be unavailable” error?

Solution 1: Switch the Browser

First, you need to test the DNS connections by switching your browser. For example. If your default browser is Google Chrome, you can switch to other browsers like Mozilla, Brave, Safari, Microsoft Edge, etc., and check whether the website is opening in those browsers.

If the website opens in other browsers, it means that the current browser you are using is either outdated or has cache issues. In this case, you can either uninstall and update to the latest version of the browser or make any other browser a default one.


Solution 2: Flush the DNS

Flushing the DNS by using the Command Prompt will ensure that the server issues are fixed. You can flush the DNS by following the steps mentioned below:

  • Firstly, press the ‘Windows + R’ hotkey and open the run dialog box.
  • Now, type ‘cmd’ and press the ‘Enter’ key.
  • When the command prompt window opens, type ‘ipconfig /flushdns’ and press the ‘Enter’ key.
  • After that, enter the command ‘ipconfig /release’ and hit the ‘Enter’ key.
  • And finally, type the command ‘ipconfig /renew’ and press the ‘Enter’ key.

After performing the above steps, it is recommended to close the command prompt window and reboot the system.
