Jicofo authentication error

Hello,
i have installed jitsi-meet but i can’t join the conference,
i don’t have any errors on javascript console, and no errors on jvb.log
I have properly set up the sip-communicator.properties

I have an error on prosody :
Jan 22 13:31:14 portmanager error Error binding encrypted port for https: No key present in SSL/TLS configuration for https port 5281

And i have authentication errors on Jicofo, but i think evry configuration is correct:
7.041 WARNING: [168] org.jivesoftware.smack.AbstractXMPPConnection.callConnectionClosedOnErrorListener() Connection XMPPTCPConnection[not-authenticated] (0) closed with error
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targe

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targe

I have cheked all the secrets and they are correct.

Someone can help me ?

Thank you

The easiest solution is to add org.jitsi.jicofo.ALWAYS_TRUST_MODE_ENABLED=true in /etc/jitsi/jicofo/sip-communicator.properties and restart jicofo.

Yes, that was the trick.
Thank you
