Help

Good mornin’,

I have a problem that I can’t get a connection if the two devices are connected via mobile internet, if they are on the same network there are no problems.

WebRTC Version: 1.75.1
React Native Version: 0.61.4

Are you using a TURN server?

Only the google stun server

{iceServers: [{url: 'stun:stun.l.google.com:19302'}]};

Does a freely accessible turn server exist for testing purposes?

I don’t know of one.
