[OpenSIPS-Users] Some calls fail with tcp_connect_blocking error on version 2.1.1

I have tested with your recommendations. Here are my findings:

i) Disabling tcp_accept_aliases increases frequency of this error.
ii) Upgrading to 2.1.3 does not resolve the issue. On this new version, I
also tested tcp_accept_aliases=0/1. I get the exact same error I posted

Is there a way we can control the number of retries opensips should make if
there is a UAC connect failure? Saying that because I know for sure that B
party has a working network connection.

I have configured the following, in case it helps you point me to the
actual issue:

modparam("proto_tls", "tls_max_msg_chunks", 8)
modparam("proto_tls", "tls_handshake_timeout", 3)
modparam("proto_tls", "tls_send_timeout", 7)
