A reader recently inquired about how to resolve the DNS PROBE-FINISHED NXDOMAIN issue.

When your browser is unable to connect to the website you’ve requested, Chrome displays this error message. This error is displayed in other browsers with different messages.

We’ll show you how to fix the DNS PROBE FINISHED NXDOMAIN error and prevent it in the future in this article.

The DNS PROBE FINISHED NXDOMAIN error can be fixed by following the steps below.

The DNS_PROBE_FINISHED_NXDOMAIN Error: What Does It Mean?

The DNS_PROBE_FINISHED_NXDOMAIN error is a Google Chrome error message that appears when the browser is unable to locate the website you’re attempting to visit.

Google Chrome error DNS_PROBE_FINISHED_NXDOMAIN

The DNS (Domain Name System) is unable to locate or connect to the website’s IP address, resulting in this error.

The website domain name is then assumed to be invalid by your browser. ‘Non-existent domain’ is what the NXDOMAIN part of the error means.

Please see our guide on how domain names and DNS work if you’d like to learn more (visual explanation).

You might think there’s a problem with your WordPress site if you get this error when trying to access it.

The good news is that your website is almost certainly up and running. Your computer is unable to connect to it, which is the issue.

Now that we’ve established that, let’s look at how to troubleshoot and resolve this issue.

What Causes the DNS_PROBE_FINISHED_NXDOMAIN Error?

The DNS PROBE FINISHED NXDOMAIN error can be fixed in a number of ways. It’s critical, however, to verify that the error is genuine.

Check that you typed the domain name correctly before proceeding.

For example, if you typed a domain name incorrectly, your browser may be unable to locate it and display this error.

You should double-check the domain name even if you clicked on a link. It’s possible that the link’s creator typed it incorrectly.

Click the ‘Reload’ or ‘Try again’ button if you’re sure the domain name is correct.

The website will reload after you click the button.

Then, to see if the problem is with your device or your WIFI connection, try accessing the website from a mobile phone (4G network).

If the website does not load on your phone, you should contact your WordPress hosting provider right away because your site is down.

If, on the other hand, the website loads fine on your phone, the problem is most likely with your computer or WiFi connection.

Let’s see if we can figure out what’s going on here.

Restarting your computer should be the first step. Turn your internet modem on and off if that doesn’t work. These steps may resolve DNS and network-related problems automatically.

If the error persists, try the methods below. Starting with the first one and working your way through them is recommended.

Check the hosts file to see if the website’s address is listed. If that’s the case, delete it along with the IP address it’s associated with. After that, save the file.
