DNS_PROBE_FINISHED_NXDOMAIN is a common error in Windows XP, Windows 7, Windows 8, Windows 10, Linux, Mac, and even Android Operating Systems.
DNS probe error may occur on one browser, mostly Google Chrome and fail to appear on other browsers like Mozilla Firefox, Microsoft Edge, and Internet Explorer.
At times, it may occur on all browsers, preventing you from accessing the internet completely. The error code may appear due to various reasons, but all of them are related to DNS server on your computer hence the name DNS_PROBE_FINISHED_NXDOMAIN.
What is a DNS server? DNS stands for “domain name system”. A domain name is a human-readable website address that you usually enter into your browser’s address to access the web page, for example, Google.com.
However, the computer does not understand where google.com is. The Internet and other networks use numerical Internet Protocol addresses (IP addresses).
Hence, Google.com is located at IP address 220.127.116.11. So you can either use the IP address or the domain name to get onto a website of your choice, but you cannot remember all those numbers.
DNS servers match the human readable names to their associated IP addresses that machines can easily understand.

What does DNS_PROBE_FINISHED_NXDOMAIN Mean?
To understand the term better, we can split it into two phrases: DNS probe and NXDOMAIN.
What is DNS probe? It is essentially making a request to the DNS servers using a domain name to find a matching IP address so that the website can load,
If at all the domain exists, if it fails to find, then DNS probe finished error is returned.
When you see NXDOMAIN error message on your browser, it means the domain does not exist after DNS probe finished hence the request could not be resolved.

Disable the antivirus, firewall or any website filtering programs if you have installed them and try accessing the website that was giving you the NXDOMAIN error.
If it fails to work, then uninstall the antivirus or website filtering programs and try again. If this method solves your problem, then you should consider finding a different antivirus or firewall program.

When accessing a website, the browser attempts to resolve the IP address of the corresponding website using cached domain names in the DNS client.
If it cannot reach the DNS server, it means the IP addresses in the cached domain names did not match, or some problem occurred, hence, it needs restarting. Follow the steps below to restart the DNS client.
