I suspect this happens because of no PING/PONG function in NOMP, but could be something else missing to complete the handshake.

Error comes from: https://github.com/RavenProject/Ravencoin/blob/master/src/net.cpp#L1434
I'm testing it with Raven coin, but most updated coins fails to complete the handshake and therefore don't relay blocks to NOMP.
I'm posting bounty for this and can also provide the testing environment where Raven & NOMP are installed and configured.
