> +Question:+
> Kurento Hello World Stuck after receiving candidates
> +Description:+
> 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:kurento at 193.147.XXX.XXX: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 ?
