Hello ,
we found this warning message that DNS is unreachable on the publisher CUCM GUI.
My version of CUCM 11.5.1.10000-6.
When I tried to resolve some hostnames from both CUCM nodes through CLI it was normally worked so DNS is not unreachable.
we run diagnostic test and we see error "reverse DNS Lookup mismatch"
Any ideas?

This is because of failed reverse lookup; a false positive if you ask me

Please verify the reverse DNS entry on your DNS server.
Please rate if helpful.
