I wonder if my question was expressed clear enough, Can anyone here give me some hint?
My jitsi meet is installed on Ubuntu server, including prosody, nginx, jitsi-videobridge etc. The Ubuntu server connects internet through a router. Behind the router is local network, with IP addresses of 192.168.1.xxx. The router forward http port 80 etc to local IP the Ubuntu server use.
If my devices (computers, tablet) access jitsi.example.com within local network, they can successfully make video and audio connections. If the devices are outside local network from another public IP address, there is no video and audio connections but there is still text communication. What could be the cause of this issue ? Is that I need to configure somewhere or this arrangement (jitsi.example.com is setup in local server and connect internet through a router) is not possible to work in current jitsi technology?
Thank you in advance.
