The last line is a reset packet from client to server, I wouldn't
expect to see a reset packet. I tried a working installation as a
test and I didn't see a reset packet.

I don't know why the client-side does this, but it's not the usual
way.

Also I noticed there were no packets with F (for finished) so that
would mean the server wasn't done sending.

Maybe first try from localhost on the PowerDNS-server ?
