[OpenSIPS-Users] Opensips tls and certificate issue

[Bogdan-Andrei Iancu]

Hi Martin,

The relevant log is:

Feb  3 06:18:36 [3626] ERROR:core:tls_accept: New TLS connection from 
123.12.28.14(my_ip):50761 failed to accept: rejected by client

So, the client opens a connection to OpenSIPS, OpenSIPS accepts the 
connection, but the connection setup fails as the client rejects the 
certificate sent by OpenSIPS.
