F5 DNS listener is not responding to queries

Hello Members, One of my F5 DNS listener is not responding to queries. I have the resolver IP listener for my local clients and a name server ip for external dns requests for authoritative zones. The external name server IP listener is not responding.

 

What could be the cause?

 

application delivery
BIG-IP DNS

    Have you tried sending a query directly to the DNS listener, just to verify functionality ? Any error logs ?
