I am running a hello-world client example from localhost.
Kurento media server is installed on Amazon ec2 instance. All TCP and UDP ports are opened.
For kurento google STUN server is configured and public IP from Amazon assigned to HttpEndPoint (announced IP)
I manage to establish socket connection and exchange iceCandidates.
UPDATE Stun server is configured in WebRtcEnpoint.conf.ini like this: stunServerAddress=stun.1.google.com stunServerPort=19302
At the time of this post this STUN seems to work fine.
The last two frames always return like this:
{"id":26,"jsonrpc":"2.0","result":{"sessionId":"4b9642c4-5d42-41e0-ba61-83698b85552f","value":null}}
{"id":27,"jsonrpc":"2.0","result":{"sessionId":"4b9642c4-5d42-41e0-ba61-83698b85552f","value":null}}
So that the value is always null.
Here is the full list of frames exchanged:
