i want to test jitsi and installed it on Debian Buster with Apache2 and on same machine with coturn. But i got in jvb.log
Health check failed in 0ms:
java.lang.Exception: Address discovery through STUN failed
In prosody.err i got:
portmanager error Error binding encrypted port for https: No certificate present in SSL/TLS configuration for https port 5281
The Server is public and I can connect with smartphone a and b, but not with a and c. It doesnt matter if c is in home wifi behind nat, or connected with isp.
I tried different Stun Server with no success and same error. Any idea?
