Does not work in LTE network and TURN server

[vtyutin]

Hello, App work pretty well when both iPhone devices are in the same WiFi network and use STUN servers from Google. Now I need one iPhone to be connected to LTE (4G) network and get connected with another iPhone connected to WiFi router. So both devices are behind NAT and I have to use TURN server for connection. What was done:

1. I installed TURN server on our server. It's configured correctly because https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ tests are passed.
2. On our server I installed and run your NodeJS signaling server. So two iPhones (one in WiFi and second in LTE network) were able to connect to signalling server and exchanged ICE candidates. But connection via TURN server can't be established.

Here is my code change to use TURN server: In WebRTCClient.swift in init function: //config.iceServers = [RTCIceServer(urlStrings: iceServers)] config.iceServers = [RTCIceServer(urlStrings: ["turn:148.76.71.179:3478"], username: "developer", credential: "my_password")]

Here is log from iOS app connected to LTE (I added print for ICE candidates local and remote):

[MostafaALZOUBI1994]

yeah bro the problem is that ice candidate sometimes arrive before the call event try to make latency when you send candidate and this will solve your problem or put an event that holds the send candidate process until the receiver is ready to receive it.
