That's bloody odd. You ought to be getting *some* input from the other
end. Two things to test:

Firstly, when you send packets to another box on the network, do they
arrive? You can test with 'tcpdump' on the remote box, perhaps?

Secondly, disable DTLS for now to keep things simple, and leave the
network idle so that keepalives and DPD kick in. Do *they* work and do
you see the traffic from the other end then?

I wonder if it's poll() on the network connection that's failing, and
never indicating that you have data on the socket?
