Why HttpRequestException in VS2015 Simulator but not Emulator

Question

I have a WinRt Universal App, and only using VS2015CTP Ultimate (no 3rd party software). The Phone Emulator connects to Azure but the Windows Simulator needs to go through an Http proxy server. I am not inside a corporate firewall. However, if I use Fiddler and have the App use its Http proxy server then the Simulator works. I'd like to not use Fiddler at all, so my question is, how do I get the Simulator to make calls to my Azure mobile service without the aid of Fiddler?

I didn't think the code would make a difference as it's the same for both phone and Windows. However, here is the code, and below that is the error.

    //In Appl.xaml, VS2015 creates this code:

public static Microsoft.WindowsAzure.MobileServices.MobileServiceClient myMobileClient = 
new Microsoft.WindowsAzure.MobileServices.MobileServiceClient(
"https://nameofmobileservice.azure-mobile.net/",
"***************************");


//I added:

private IMobileServiceTable<MyResultData> GetMyResultDataTable()
        {
            IMobileServiceTable<MyResultData> myResultDataTable = null;
            try
            {
                myResultDataTable = App.myMobileClient.GetTable<MyResultData>();
            }
            catch (System.Exception e)
            {

                System.Diagnostics.Debug.WriteLine(e.InnerException);
            }
            return myResultDataTable;
        }


//This is the call that fails in Windows simulator, but works in phone emulator:

 public async Task InsertTacticResultData(MyResultData data)
        {
            IMobileServiceTable<MyResultData> myResultDataTable = GetMyResultDataTable();
   try
            {
                await myResultDataTable.InsertAsync(data);
            }
            catch (System.Exception e)
            {
                System.Diagnostics.Debug.WriteLine(e.StackTrace);
                System.Diagnostics.Debug.WriteLine(e.Message);
                System.Diagnostics.Debug.WriteLine(e.InnerException);
            }
        }
