Need help SIP not working

hey i installed everything like its discribed in the quickstart

but when u try to call out i get the following errors :

2020-03-19 11:52:18.130 SEVERE: [95] impl.protocol.jabber.ProtocolProviderServiceJabberImpl.connectAndLogin().1003 Failed to connect to XMPP service
i think it is a Problem with the certificate . but i am not shure please help

This is an xmpp provider not sip. Maybe giving more context and pasting the whole log will help show you the problem.

Thanks for the Correction
i figured it out , it was a missing certificate
