Ah... I already had that but I see now that the problem is due to the 
14.1 issue I reported (see  "FreeBSD 14.x localhost source address" on 
the freebsd-stable list).

So I changed named.conf and now it works!

--- named.conf  (revision 72)

  controls {
         inet 127.0.0.1 port 953
-               allow { 127.0.0.1; } keys { "rndc-key"; };
+               allow { 127.0.0.0/8; } keys { "rndc-key"; };
  };

Looks like I need to create a PR for this issue.
