Please include any listen-on { ... } and listen-on-v6 { ... } clauses.
It seems any of 127.0.0.1; ::1; nor localhost; is listed in them.
Because it is not listening on localhost socket, it would not answer any
queries.
If the server should listen on all interfaces, just use:
listen-on { any; };
If it has addresses on which it should not listen, just add localhost;
to current listen-on.
It might be able to respond to:
dig @91.216.35.21 -b 127.0.0.1 localhost
Which would be technically from localhost, but I guess you are looking
for listen-on change.
Cheers,
Petr
