401 engedélyezési hiba Windows Phone 8 értesítések

Megpróbálok értesítéseket küldeni a Windows Phone 8 alkalmazásomnak egy hitelesített szerver használatával, de 401-es hibaüzenetet kapok, amikor megpróbálok értesítést küldeni.

Követtem az MSDN-oldalakon található utasításokat, nevezetesen: http://msdn.microsoft.com/library/windows/apps/ff941099(v=vs.105).aspx ahol ez áll: The Key-Usage value of the TLS certificate must be set to include client authentication. Fogalmam sincs, hogy ez mit jelent, és az online keresés nem adj nekem is bármilyen nyomot.

Lehetséges, hogy ez hibás, vagy az én kódom, ami lent látható.

VB.NET-KÓD:

Ez a várt módon működik, és az URI az adatbázisomban van tárolva (HTTPS-sel kezdve, és az URI-ban sem tartalmaz throttledthirdparty-t, ami arra utal, hogy ez a kód működik).

Hiba lehet a kódomban, vagy az lehet, hogy nem állítom be megfelelően a backend dolgokat (a legtöbb MSDN-dokumentum a Windows Serverekre és az .aspx-re vonatkozik, ezért megpróbáltam replikálni ezeket az utasításokat, de lehet, hogy Valahol elromlott!).

Ha valaki tudna segíteni akár a kódhibák kijavításában, akár az SSL tanúsítvány kliens hitelesítésében, azt nagyon megköszönném!

Köszönöm, Jake
