[Freeipa-users] DNS issues

So I've had my FreeIPA setup for about 6 months now at my company.  As of recently i'm seeing some issues where if I try to dig against the servers I get nothing back.  I do not have a global forwarder setup because it should automatically go outbound if its not in its own table, correct? This only seems to be an issue on 2 out of 4 of my servers.   Also my forwarding policy is forward first.   My environment has 2 IPA servers in my local office and 2 IPA server in my AWS VPC.  We have a legacy domain that I am forwarding to our legacy nameservers until those get turned off. There is not much in the logs to tell me if there is an issue (at least that I can see).  Usually a reboot helps but that can't be the answer all the time. Any thoughts? All 4 servers are running CentOS 7.4FreeIPA version 4.5.0 Thanks!
