Mobile clients cannot see video

Hi, i need some help on figuring out why the mobile clients cannot see desktop user’s video with the Android app. Their own video is working for the desktop users, and between desktop users there are no problems.

All the firewall ports are allowed, currently there are no filters in INPUT/FORWARD/OUTPUT.
The server uses Let’s encrypt certificate.

mobile user join in jicofo.log: http://p.ip.fi/n_MD (replaced domain with example)
mobile user join in jvb.log: http://p.ip.fi/xRfk (replaced domain with example and IP address with 111.111.111.111)

Here are the versions:
jitsi-meet 1.0.4130-1
jitsi-meet-prosody 1.0.3753-1
jitsi-meet-web 1.0.3753-1
jitsi-meet-web-config 1.0.3753-1
jitsi-videobridge 1126-1
jitsi android app 19.4.0 build 2734091

nginx config: http://p.ip.fi/Btkh

Is your server running on the public address or it is behind nat and ports are forwarded?

When testing with desktop you are not in the same network with the jvb, right? I mean that connection goes over Internet the same way as the mobile?

Also make sure the whole chain of certs is available as this may prevent mobile clients to connect.

It is running public address and the clients are on a mobile connection (4G).
The desktop clients are on the internet, the same as the mobile clients.
