Hi Kusuma, Connection oriented transports, i.e., tcp, tls and quic, for the echo clients are probably often tested, udp most probably not (especially with loss). In your case, you are also trying echo clients in full-duplex mode and that’s most probably not going to work with udp. Try adding “no-return” option.
Also, echo clients only works with one transport at a time.
