To check your server's resolvers, run the following command, where
example.com represents a domain on your server:
If this command did not return results, the
/etc/resolv.conf file does not contain resolvers. Use WHM's Resolver Configuration interface (Home >> Networking Setup >> Resolver Configuration) to add resolvers to your server.

If these commands fail, make certain that you used the correct IP addresses. Then, run the following commands to find the problem:
18.104.22.168 with the desired resolver's IPv4 address.
2001:4860:4860::8888 with the desired resolver's IPv6 address.
