I was conducting a small test with a friend and we had some issues.
ubuntu 18.04, jitsi unstable, nginx, secure domain enabled, p2p disabled, no turn server (for now)
4 vcores, 8GB ram, 200Mbit in\out
User 1 (me,a host): PC, win 10, chrome browser, +audio+ screensharing
User 2( my friend, he lives in UAE, so firewalled) - macbook pro,chrome\safari (latest) audio enabled
Audio and screensharing works
I added another user (user3) using my smartphone connected to my wifi
user3: android, jitsi app, audio+webcam enabled.
I could hear myself talking via a smartphone and see myself on my PC, but my friend didn’t see my webcam and didn’t hear me talking.
He tried then using a VPN but it didn’t help.
What could cause this? Is it because I don’t have a turn server?
