[dnsdist] dnsdist not seeing a valid port

[Otto Moerbeek]

Hi,

Can you query the recursor with dig @::1 -p 5301 ... ?

If you get a timeout, it is likely an ACL isue on the recursor side,
recursor will drop queries from non permitted clients.  See
https://docs.powerdns.com/recursor/settings.html#allow-from


If so, use setVerboseHealthChecks(true) in the dnsdist configuraion
to get detailed health check information to diagnose further.
