Most of the times this error “This site can’t be reached www.example.com’s server IP address could not be found. DNS_PROBE_FINISHED_NXDOMAIN” comes when you change your website nameservers or DNS settings for any reason, like to redirect your naked domain (example.com) to www (www.example.com).

After changing the DNS settings of a website when you browse to test the changes you might get the above error. You will also notice that all other websites will open except yours or specific website.

Most of the website owners or bloggers when they see this error get panic by thinking that, “Oh, what happened. My website is down, now what should I do?” You don’t need to get panic because this error is only on your computer browsers.

If you want to test that this error is only at your side, you can turn on the VPN like “Browsec VPN or VPNCity“, and browse that website.

You must have an idea about DNS (Domain Name System). It translates your website domain names to IP addresses. It was difficult for the humans to remember the IP addresses of websites, so user-friendly domain names are used for browsing websites like Google.com, meersworld.net, etc. An IP address is used to uniquely identify the computers on internet.

The solution to this error is by setting the Google Public DNS IP addresses as your DNS servers in your TCP/IPv4 Properties. Public DNS is a name resolver. The benefit of using Google Public DNS is that it speeds up your browsing experience and improves security.
