Issue with pixel streaming server's configuration

I would like to also jump in and say I am in the exact situation. I can access locally the unreal instance, and remotely I can access the web “front end”.

Internally: I type the local IP “192.100.100.237” and it loads, as well as the external IP “173.XX.XX.196” and it loads up.

Externally: I type in the external IP of our network, firewall is set up to forward to a internal machine, the HTML site loads and says “Click to start”, and then “Starting connection to server, please wait…” remains.

my config.JSON

{
“UseFrontend”: false,
“UseMatchmaker”: false,
“UseHTTPS”: false,
“UseAuthentication”: false,
“LogToFile”: true,
“peerConnectionOptions”: “{ “iceServers”: {“urls”: “stun:173.XX.XX.196:19302”]}] }”,
“HomepageFile”: “player.htm”,
“AdditionalRoutes”: {}
}

Not sure what to do here.
