The DNS lookup failed error is a net connection error. The Google Chrome error message states This webpage is not available… The server at… can’t be found, because the DNS lookup failed. Consequently, users can’t open any website pages in Chrome.

Learn how to fix this below.

What to do if the browser stops working after DNS fail?

1. Consider using a different browser

If Google Chrome persists in showing you the error message even after you tried all troubleshooting solutions, you should try using a different browser instead.

If you’re a fan of Chromium-based browsers like Google Chrome and Microsoft Edge, then we recommend you switch to Opera.

Not only is it incredibly powerful and lightweight, but it is also extremely stable, receiving updates after updates that constantly maintain in in peak condition.

It also comes with extremely useful tools, such as a built-in ad-blocker, or a VPN, allowing not just an error-free browsing experience, but also a private one.
