I have installed Jitsi Meet on my own Ubuntu server following this tutorial step by step and everything is ok.
I have not used dns name (my public IP directly). and I used the option of
self-signed certificate (let’s encrypt).
From a PC with Chrome, when I access my public IP, I receive the typical warning that the certificate is not valid. After that warning everything works correctly. I have created a room and from other pcs (with Chrome too) and with different networks everything works great.
However, in Android and iOS does not work. In both receive a black screen
Could it be because the certificate is not trusted? If I make the demo of the web of jitsi works everything correct (iOS and Android)
Thanks in advance and sorry for my english!
