Just a thought, but have you tried one of the geographical pools
({eu,na,oc}.pool.sks-keyservers.net) instead of the general one? that
should result in better network response time and routing.

This keyserver is wrongly configured, as it doesn't respond on all
traffic on port 11371 but filters it based on Host header (the server
operator is BCCed to this email), so it currently does work using the
pool.sks-keyserver.net but not keys.gnupg.net

There is no "official source", nor any requirement to publish keys on
a keyserver, either private nor public. It is often convenient to do
so, though (but the existence of a key on a keyserver is no indication
of validity of the key, so this will always have to be verified out of

$ dirmngr
OK Dirmngr 2.1.9 at your service
