Communicate with embedded HTTP Server via XTC_APP_ENDPOINT

Question

I'm referring to the implementation outlined in this video: https://www.youtube.com/watch?v=mnAenNaEpJk

This works fine running locally using the IP address of my device over any port (as long as the client and server use the same port).

Test client:

var url = isTestCloud ? Environment.GetEnvironmentVariable("XTC_APP_ENDPOINT") : "http://" + deviceIp + ":8081";
HttpClient client = new HttpClient {
    BaseAddress = new Uri(url),
};

In App:

HttpListener _listener = new HttpListener();
var prefixes = new [] {
    "http://*:8081/",
};
foreach (string s in prefixes)
    _listener.Prefixes.Add (s);
_listener.Start ();

This works great running locally, but when trying to run in Test Cloud, I get a System.TimeoutException in my Test while trying to connect to the game server.

From the video, James makes it clear that you must be listening on port 8081, however this was a couple of years ago and I'm wondering if it has changed. I also tried changing 8081 to 37777. But I still had the same result.

I noticed the XTC_APP_ENDPOINT env variable returns something like: http://devicehost7.prod:37777/wd/token-1acaf8c0-2987-4a49-aa5b-3ab795ecb910/

I adjusted my server to use 37777, same result. I tried again adjusting my prefix: var prefixes = new [] { "http://*:37777/*/token-*/", };, but always get the same result (System.TimeoutException).

Is there any documentation I can read up on regarding how to interact with an embedded HTTP server? Or can someone point me in the right direction?

Thanks, Loren

After speaking with support, it seems TestCloud was producing an incorrect value for XTC_APP_ENDPOINT.

They've addressed it, and now my original code now works perfectly over port 8081!
