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 are constantly maintained 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.

A web browser that balances out stability, performance, a high level of customization, and low system requirements.

2. Clear Chrome’s cookies and cache

  1. Clearing Chrome’s cookies and cache might erase misconfigured browser data, which can potentially resolve the “DNS lookup failed” error. To clear Chrome’s cache, click the Customize Google Chrome button.
  2. Select More tools and Clear browser data on the menu to open the window shown directly below.clear chrome's cache browser dns lookup failed
  3. Click the Advanced tab.
  4. Select All time on the Time range drop-down menu.
  5. Select the Cached images and files, Browsing history, and Cookies and other site data checkboxes.
  6. Then press the Clear data option.

If the manual method seems like too much of a hassle, you could always opt for a third-party PC cleaner. This type of tool will scan your browser for unnecessary clutter and let you know what can be removed.

Alongside cleaning your browser, dedicated cookie cleaners generally include other PC optimization tools such as registry cleaners and startup editors.

On top of that, some browser cleaners will help you remove unwanted toolbars and plugins, remove spam/useless emails, and more.

We gladly recommend CCleaner from the list of software we tested, which performs thorough cleaning, as one of the best tools for this task.

CCleaner makes it simple to get the most out of your computer because PC maintenance has to be at the top of the priority list. Furthermore, if you can tune up your computer on a regular basis, you’ll be more satisfied with its overall performance.
