Of course! There was extra coockie verifying in packet handling. So thank you for your help and sorry for disturbing. I'll post the client's hangs issue to the bugtracker.

Gnutls: REC[0x65ddbb0]: INVALID VERSION PACKET: (-1) 254.255
The comment on that error states:
"Reject record packets that have a different version than the one negotiated"

You'd better see with wireshark the versions negotiated and placed in
record packets.

Hmm strange, but server partly send dtls 1.0 packets ant partly - 1.2 packets. The client sends first packet with dtls1.0 packets and then - 1.2 packets. 99% for that I'm doing something wrong, but I'm luck of idea. Maybe you have a couple of minutes glance on the pcap in attachment? There are some malformed packets, but I don't know what to do with that information.

P.S. I'll compile a code from example in an hour for that and 0-timeout issues.

Kind regards
