Hello everyone!

After hours of debugging I found out it actually seems to be a bug in =
the
TLS interface of unbound 1.9.0.2
I just patched to unbound 1.13.1 from buster-backports and now it works.

Thanks for your help!

Best regards
Patrick Prugger

There's no error here and this host does indeed work fine with a =
validating
recursive resolver.

geo.freebsd.org is delegated to a separate set of nameservers which =
handle
geo-based replies.  DNSSEC is intentionally not present on the zone as =

software that responds with dynamic replies and does not currently =
support
signing those.

You should investigate your setup a bit more.
