Audiovisual MediaStreams are destroyed in some networks: "NOVIABLEICE"

[jimver04]

Hi Vincent,

in general NAF is working well in any network I have tried. However,

@Mobile, Android 11, Mobile Chrome or Firefox, in a certain public network I get "NOVIABLEICE" and easy-rtc closes MediaStreams. I see that entities are created across peers but mediastreams are automatically destroyed. Any idea ?

This does not happen using Chrome@PC in this network. I suspect that

• there is a setting in mobile devices for such networks and for MediaStreams specifically ?

I will look into it.

Also @hthetiot might know the answer.

My easyrtc-server.js contains the following setting regarding ice/stun

// Start Socket.io so it attaches itself to Express server
const socketServer = socketIo.listen(webServer, {"log level": 1});
const myIceServers = [
  {"urls":"stun:stun1.l.google.com:19302"},
  {"urls":"stun:stun2.l.google.com:19302"},
  // {
  //   "urls":"turn:[ADDRESS]:[PORT]",
  //   "username":"[USERNAME]",
  //   "credential":"[CREDENTIAL]"
  // },
  // {
  //   "urls":"turn:[ADDRESS]:[PORT][?transport=tcp]",
  //   "username":"[USERNAME]",
  //   "credential":"[CREDENTIAL]"
  // }
];

Best,
Dimitrios

Hi,
The message is self explanatory, there is no viable ice candidate to make the connection.
You need to configure a turn server, see

I have found a public turn server that did the job. It is useful for those that want to run NAF in public wifi networks using mobile devices !!!

😏

const myIceServers = [
    {
        urls: "turn:openrelay.metered.ca:80",
        username: "openrelayproject",
        credential: "openrelayproject",
    }
