named BIND 9.18.33 (Extended Support Version)
I upgraded the hardware on an old (12 year) system that was functioning adequately, so that I can upgrade the OS to LEAP 16. The transition went well but for DNS issues.
The named configuration has not changed in any way. Only the hardware changed.
The firewall’s public zone allow DNS traffic. As it did before the hardware change.
Any suggestions what may be causing this?
The startup log is below. It looks good except for resolver priming query complete: timed out. Something is preventing all outgoing DNS queries. For instance, this blocks outgoing mail, network time requests, browser traffic, any service that runs locally and requires a DNS resolution.
I can SSH to the host. It can resolve local (internal) DNS queries.
