This is called DNS name resolution and involves a DNS recursor querying various nameservers to figure out the actual IP address of a server. When a user enters a URL in their web browser, DNS gets to work to connect that URL to the IP address of the actual server. Essentially, it takes a human-friendly request – a domain name like – and translates it into a computer-friendly server IP address – like 216.3.128.12. The reason for DNS_PROBE_FINISHED_NXDOMAIN is typically due to a misconfiguration or problem with your DNS. DNS is short for Domain Name System, which helps direct traffic on the internet by connecting domain names with actual web servers.
This can also work for other browsers, such as Firefox, Edge, etc. Check out the recommendations below on how to get connected again.
