HttpWebRequest(GET) works on emulator, doesn't work on device

Question

I'm writing a little game for windows phone. It puts scores of everyone to mysql database(using php) and gets the best score. Everything works fine on the emulator, unfortunately it does not work on the physical device.

Here's the code for getting the best score:

    public static void retrieveBestScore()
    {
      string uri = "https://xxxxxx.net/get_scores.php?sort=score%20DESC&count=1";
      HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(uri));
      request.BeginGetResponse(new AsyncCallback(ReadCallback), request);
    }

    private static void ReadCallback(IAsyncResult asynchronousResult)
    {
        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
        [...]
    }

ReadCallBack method if fired, but asynchronousResult's AsyncWaitHandle parameter is

base = {System.NotSupportedException: Specified method is not supported. at System.Net.Browser.OHWRAsyncResult.get_AsyncWaitHandle()}

I've read somewhere the problem may be caused by using https instead of http, but it's not the case here.

Do you have the `Internet (Client & Server)` Capability on in your app manifest? — Benjamin Diele, Jul 22 '14 at 20:23
I do have Networking capability checked. As I said- everything works great on emulator. — Michał Żołnieruk, Jul 22 '14 at 20:30
Using your code, I can get the `HttpWebRequest request` without a crash. Have you tried it in a new SL app? — Benjamin Diele, Jul 22 '14 at 20:37
I just did with the same result. Are sure you tested it on a device? — Michał Żołnieruk, Jul 22 '14 at 20:48
Yes, I'm sure :) What version of windows are you targeting? My test project is WP8.1. And I think i'm using a SilverLight app, but I can't find it in VS. — Benjamin Diele, Jul 22 '14 at 20:51
I've tested it on 8.0 wp, my original project is targetting monogame 8.0 :/ — Michał Żołnieruk, Jul 22 '14 at 21:03
