Some of the server’s DNS resolvers fail to respond.

Usually it means that the resolver IP address mentioned as a.a.a.a has some timeout issues.
Thats why WHM notifications sending out. Usually we can either remove this resolver or can use an alternate one.

Error shows that one of the resolver failed ( a.a.a.a failed) . Just ping/telnet to that IP address to check whether it is down.

1. Log in to WHM

2. Go to Home » Networking Setup » Resolver Configuration

Here you can remove the resolver that is having issue or you can add a new one.

3. Click on 'Continue'

You can also add/remove resolver IP from server backend by editing the /etc/resolv.conf file.
