Someone has installed a ordinary recursive server as a transparent
DNS caching server and is intercepting your queries. This does not
work.
At a minimum a "transparent" DNS caching server needs to force
recursion. It also need to fake AA=1 in the responses. It also
needs to pass through TSIG signed queries. It also need to pass
through SOA/AXFR/IXFR requests.
You should be able to work around the issue by forwarding all your
queries. That way "rd=1" will be set on them and you won't be
expecting "aa=1" responses.
e.g.
forward only;
forwarders { 8.8.8.8; };
