Hi Tito,

Well, from OpenSIPS perceptive it is a "Connection refused", so the destination is rejecting the connect.

It closes the socket right after the syn+ack. I can provide the trace if necessary.Here is an output of the logs

    Hi Tito,

    You say OpenSIPS is sending a RESET without being any data
    exchanged on the connection?

    What are the logs for the failed send ?

    Hello,

    I am attempting to use t_relay("tls:domain:port") but I am not
    having much success with it on 2.4. opensips sends a syn  to the
    peer then gets an syn ack and sends a rst . The logs claim that
    the send failed but it never opened the socket entirely and did
    not send the client hello at all.

    Are there any other configs to be considered when attempting this ?
