first check, unbound is running and do listen for queries:

# id -u -n

# netstat -lnpt | grep 55
tcp        0      0  *               LISTEN      4711/unbound       

next: you need to adjust access-control, add "access-control: allow" to your unbound.conf
and restart unbound.

That should at least allow the query above from the host itself.

man unbound.conf say: By default only localhost is allowed, the rest is refused.
... And is not localhost ...

> root at ubuntu:/etc/unbound/unbound.conf.d# nslookup -port=55
last: please favor dig over nslookup

# dig -p 55 unbound.net. A @

otherwise post unbound logs, the output of the command and your unbound.conf.
