Thanks All for the suggestions. I was still using iptables - not firewalld - I did miss the UDP port 53. That was my issue.
Your mileage may vary, but usually when I fiddle with a new service that I don't know well, I start out by disabling the firewall, putting SELinux in permissive mode or deactivating it altogether.
Then, when things start working as expected, I'll add them again progressively until everything works perfectly.
