The ERR_NAME_NOT_RESOLVED error usually appears on Google Chrome on computers or Android phones. There are many reasons for the above error when you browse the web.

Here are a few common and useful methods to help you fix the above error.

Step 1: Delete your browsing data (Google Chrome)
Chrome stores data on all the websites you have visited in the past by default. This cached data helps pages load faster when reloading them and auto-completes addresses as you type. As useful as this function is, it can quickly become a problem and result in the “ERR_NAME_NOT_RESOLVED” error when using Android, Windows, and so on. A possible solution is thus to delete all your browser data. To do this, open the Chrome menu using the three-dot icon and select “More tools”. Then click “Clear browsing data”. In addition, please turn off the Preload pages for faster browsing and searching feature on your browser. Please see detail image as below:
