[Jitsi Desktop] Call ended by remote side. Reason: incompatible-parameters. Error: offer container no media format or no valid media descriptions

Me and contact of mine created an account each with a XMPP server, then installed Jitsi Desktop and managed to find each other through the client.

We were able to exchange chat messages, but we weren’t able to have audio calls, video calls, screen sharing sessions (the latter being what we were really after).

The message we kept getting is the one as per the title. I’m a complete beginner so please bear with me, but does that message mean that the server we selected does not support anything other than chat, or was it a matter of something being mis-configured in our clients?
