asp.net-mvc-4 - Azure 上的 PushSharp ASP.net MVC4 问题。 - 无法连接APNS反馈服务

Question

我有一个 ASP.Net MVC4 网站，在 Azure 上运行一个简单的 Web 服务，为我们的移动应用程序提供推送通知服务。它在我的计算机上的本地 IIS 实例上运行时可以工作，但一旦部署到 Azure，它会工作一段时间然后停止。看来PushSharp无法连接到Apple的反馈服务后可能会停止。最初我得到第一个堆栈跟踪，然后每隔十分钟我得到第二个。这些证书可以很好地连接到 APNS 本身，实际上我已经收到了通过 Azure Web 服务发送的测试推送通知。我正在从文件加载证书，如 PushSharp 示例中所示。我是否需要另一份证书才能进行反馈服务​​或其他什么？还有其他人有类似的设置吗？

这似乎是相关的。 https://github.com/Redth/PushSharp/issues/49

Azure 网站的免费或共享模式将导致此问题。

扩展到保留模式(如果可以的话)，问题就会消失。
