Have you ever clicked on a website and it said “this site can’t be reached”, along with “dns_probe_finished_nxdomain” or “server dns address could not be found” and wondered what it meant or how to fix this error? Is your first instinct to call someone who knows about tech or is in I.T? Stop right there!
What is “DNS_PROBE_FINISHED_NXDOMAIN”?
To understand what this error code means you need to understand what happens when you make a web search. When you type a URL into your web browser, the DNS, or Domain Name Server translates the Domain Name into the corresponding or matching IP address so that you are able to access the website you wish to visit. This is because IP addresses are not so easy to remember, for instance, the domain name for something may be microsoft.com, but the corresponding IP address is 184.108.40.206
What Causes “DNS_PROBE_FINISHED_NXDOMAIN” Error Code?
The DNS does not always successfully translate the Domain Name and as a result, you will see the “dns_probe_finished_nxdomain” error code.
Please note that there are other error codes beginning with “dns_probe_finished….”. But whenever you see “NXDOMAIN” at the end, it simply means Non-Existent Domain).
Now that you know what the error code means and what causes it, it is time to explore some possible solutions:
