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. Essentially, it takes a human-friendly request – a domain name like kinsta.com – and translates it into a computer-friendly server IP address – like 22.214.171.124.
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. This is called DNS name resolution and involves a DNS recursor querying various nameservers to figure out the actual IP address of a server. If DNS fails to resolve the domain name or address then you might receive the DNS_PROBE_FINISHED_NXDOMAIN error
There are simple steps that can lead to solving these problems. It is likely that you would not require any expert help because you can perform many of these techniques by yourself. The following are some of the steps you can adopt for solving the error DNS_PROBE_FINISHED_NXDOMAIN:
Alter the DNS IP address
Flushing the DNS
Restarting the DNS Client
