Try forwarding TCP port 5222 on your router to the unraid server internal address. May have to also map it for docker in unraid. For Jitsi you need ports 443 for https, 80 for http, UPD 10000, and TCP 5222. You can of course remap these to none standard points in your router as Unraid already uses 80 and 443. Here's a link to the jitsi documentation also. https://github.com/jitsi/jitsi-meet/blob/master/doc/manual-install.md
