When trying to get reverse DNS on a few of my addresses, I get this from DNS Stuff:
"[Broken DNS server: Reports a server failure]"

The zone and files look fine. I even deleted and recreated a zone and still get the same error.
We have one full cPanel server and two DNSONLY servers, all clustered.
I searched the forums and did not find any answers, so sorry if this has been asked before.
Any ideas?
