I followed a tutorial from webrtc-experiement website and installed the coturn on my local ubuntu virtual machine.
I set up the listening ip and external ip with the ubuntu private ip 192.168.47.131 and the port is 3478 and 5349 for secure address (i don't have the cert yet so i commented those ssl)
But my webrtc app (also run on local) keeps telling turn server broken with my iceServers configuration: { credential: "test", url: "turn:192.168.47.131:3478", username: "test" }
I am able to get connected from my windows 10 to this turn server on udp, tcp. Does it have to be a public ip?
