coturn
can't access STUN/TURN server from webrtc
I am following the official coturn docs and trying to setup a coturn server to handle STUN and TURN requests. I am testing if my server runs correctly by using this little JS script:
function checkTURNServer(turnConfig, timeout){
return new Promise(function(resolve, reject){
setTimeout(function(){
if(promiseResolved) return;
resolve(false);
promiseResolved = true;
}, timeout || 5000);
var promiseResolved = false
, myPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection //compatibility for firefox and chrome
, pc = new myPeerConnection({iceServers:[turnConfig]})
, noop = function(){};
pc.createDataChannel(""); //create a bogus data channel
pc.createOffer(function(sdp){
if(sdp.sdp.indexOf('typ relay') > -1){ // sometimes sdp contains the ice candidates...
promiseResolved = true;
resolve(true);
}
pc.setLocalDescription(sdp, noop, noop);
}, noop); // create offer and set local description
pc.onicecandidate = function(ice){ //listen for candidate events
if(promiseResolved || !ice || !ice.candidate || !ice.candidate.candidate || !(ice.candidate.candidate.indexOf('typ relay')>-1)) return;
promiseResolved = true;
resolve(true);
};
});
}
and running it with my credentials:
checkTURNServer({"url":"turn:IP1:3478",'username': 'bayaz',"credential":"magi"}).then(function(bool){
console.log('is TURN server active? ', bool? 'yes':'no');
}).catch(console.error.bind(console));
Where the user was created with;
turnadmin -A -u bayaz -p magi
This are uncommented lines in configuration file:

This is the output of running turnserver -c path/to/file.conf

When I test my turn server, I get my custom error message "is TURN server active? no" in the console, which indicated that I got no response from the server.
I already spent a few days trying to figure this out, but I had no luck. What am I missing here? Another thing that I didn't fully resolve is that mysql is not supported, even though I yum installed mysql-devel and mysqlserver. Why is that? In the INSTALL file it says that shared library should be set (LD_LIBRARY_PATH), but I am not sure what do to with it. I am on Centos 7.
Hi @mittster and @Prashanth004 Do you still have an issue? I suggest to test your server with https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ or turnutils_uclient first (to make sure your coturn is properly configured and accessible)
On the other hand, you can test your simple test app with publicly availabe turn servers (to make sure your JS app does not have bugs)
