#8475 — DNS issues in private network

SubjectDNS issues in private network
Message-ID<20240412150500.000062b6@gmail.com>
I have a rather new, minimal installation of Rocky Linux 9 (so
effectively RHEL 9) and have a pihole running on another machine in my
private network. I have changed the nameservers on the Rocky Linux
machine to resolve via the pihole DNS on the local network. 
All of a sudden the DNS stops resolving. 

; <<>> DiG 9.16.23-RH <<>> google.com
;; global options: +cmd
;; connection timed out; no servers could be reached

Network connection still is there, only DNS resolution is affected. I
can ping the other machine. The pihole is running and it is resolving
for other machines, it just doesn't seem to work on this particular
machine. 

Anyone got an idea what the issue might be?

Start with:

host -v google.com pi.hole.ip.address

I had to install Rocky Linux 8 for other reasons and that solved this issue
