For those of you who work with WordPress regularly, CMS-specific errors, such as the white screen of death or database connection errors, are common. But another subset of errors you’re likely to encounter are those related to your internet connection and DNS. One very common error Google Chrome users get when trying to navigate to a website is DNS_PROBE_FINISHED_NXDOMAIN. This can be downright frustrating as you suddenly can’t access your website or anywhere at all.

If you see this error while trying to get to your WordPress website, don’t worry, it’s pretty easy to fix. Check out the recommendations below on how to reconnect. This may also work for other browsers such as Firefox, Edge, etc.

What is DNS_PROBE_FINISHED_NXDOMAIN?


The reason for DNS_PROBE_FINISHED_NXDOMAIN is usually a misconfiguration or a problem with your DNS. DNS is short for Domain Name System, which controls traffic on the Internet by connecting domain names to actual web servers. Essentially, it takes a user-friendly request – a domain name like kinsta.com – and it translates it into a computer-friendly server IP address – like 216.3.128.12.

When a user enters a URL in their web browser, DNS works to match that URL with the IP address of the actual server. This is called DNS name resolution and involves a DNS recursor that queries various name servers to find out the actual IP address of a server. If DNS cannot resolve the domain name or domain, the DNS_PROBE_FINISHED_NXDOMAIN error may be displayed. The NXDOMAIN part stands for Non-Existence Domain. Read more about DNS and how it works.
