[iodine-users] iodined: header->qr does not match the requested qr

Sounds like you are getting replies instead of questions to your server.
Are you running the client from the same network as the server, with a
remote nameserver in between?
It seem your network or DNS setup is wrong. Try recording the network
traffic from both the server and clients point of view.
