          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@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 ?

          TURN Server :
