Jitsi video call not working cross platform

When I start a Video call on PC or on Mobile device to one or the other. The call is made and can hear each other but not able to see. It works fine Tablet to Tablet or PC to PC. Is there something on the backend that needs to be done?

This is running on a Ubuntu 20 Private server. Jitsi is running on the same server out port 444.

Done some reaserch on the topic and have been unable to find a fix.
