iceConnectionState goes from *checking* to *failed*

[tufik2]

Any solution for this issue? I am having the same issue in Android Simulator trying to connect with other Peer using the web (Chrome), but no matter what I tried, always status keeps checking > failed… I just need to use DataChannel so my configuration is…

I am using peerConstraints = {iceServers: [{urls: ‘stun:stun.l.google.com:19302’}]};
and offerConstraints = {offerToReceiveAudio: false, offerToReceiveVideo: false};

You either have a race condition with processing the ice candidates or you'll need a TURN server.
Best to always have a TURN server along side a STUN server though.
Have a look over here in relation to the candidate handling, hopefully helps.

The Android simulator runs on a different network, it's likely STUN alone doesn't cut it.
