[OpenSIPS-Users] OpenSIPS 3.6.5 Debian 11/12 Issues tls_openssl and auth module

[Răzvan Crainea]

Hi, Jonathan!

Running OpenSIPS in combination with openssl 3.x may lead to unexpected 
behavior like you've mentioned. There have been several discussions 
around this, that's why we decided to do a complete rework in 4.0 [1].
In the meantime, if you are stuck with 3.6, you may give tls_wolfssl a 
try, it might temporarily sort out your problems.
