Kurento Hello World Stuck after receiving candidates

Question

I am trying to setup a Kurento media server behind an nginx proxy & testing with the Kurento-hello-world example. The TURN server is in place & Kurento is up.

I added the TURN url in file /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini as explained here

turnURL=kurento:[email protected]:3478

I opened the specified ports :

3478 TCP & UDP
49152-65535 UDP

EDIT : I notice TURN is announcing a remote HEAD IP that seems to be in my network, but is not linked to my project and never specified in configs, as seen in the browser console, I receive a candidate 2 with the unknown external IP and a candidate 3 with good external IP but wonder if the browser can be stocked trying to connect to a bad one. Is it possible to avoid TURN propose a specific address ?

Locally, I can see (netstat -tulpn) the candidates UDP ports allocted on both kurento & TURN machines. The video input that should come from the server never appears, meaning the Connection is never achieved ?

TURN Server :

Can you please say which exact version of KMS and browser (version and type) you are using? The command dpkg -l | egrep -i "kurento|gstreamer|nice" should help you — igracia
Hi @igracia, I added packages version to the quextion. I tested with same results on both Chrome Version 48.0.2564.41 beta (64-bit) & firefox 43.0b9. — jbheren
Ok, there's no incompatibility between those versions. Try opening all UDP ports. STUN will use any available UDP port, the range you have defined is just for TURN (we need to fix that in the documentation), and it might be the case that the STUN candidate is outside of that interval. — igracia
Thanks @igracia I extended the port range but it has no effect, in fact when I check the opened UDP ports with netstat -tulpn, those are in the range. I have TURN & NGINX services installed on font server with web address & Kurento is on a second server with local & internet access, could it be an issue ? Seems like TURN is made for that. I can see also that kurento is waiting for connection, but TURN displays a different IP address as remote than itself. — jbheren
Cool! Thanks for the update. I think updating that image to the lates Kurento doesn't work that well, that's why the fresh install did. Probably some dependencies didn't get installed right. — igracia
