无法打开频道（推送通知） [英] Failed to open channel (push notification)
问题描述
在3/6之前，我可以通过以下代码打开频道来测试推送通知到我的应用。
Before 3/6, I am able to open channel to test pushing notification to my app by the following code.
但是，我总是无法打开channel（从调用CreatePushNotificationChannelForApplicationAsync时获得错误）来自3 / 6.
But, I am always failed to open channel (get error when calling CreatePushNotificationChannelForApplicationAsync) from 3/6.
例外显示
The exception shows
"类型'系统的例外。 Runtime.InteropServices.COMException'发生在rnu-pushno2.exe中，但未在用户代码中处理
"An exception of type 'System.Runtime.InteropServices.COMException' occurred in rnu-pushno2.exe but was not handled in user code
其他信息：网络不存在或未启动。 （HRESULT异常：0x800704C6）
"
Additional information: The network is not present or not started. (Exception from HRESULT: 0x800704C6)
"
但是，我确信我的Windows 8能够连接互联网，并通过3.5G网络进行双重测试没有公司网络政策。
However, I am sure my windows 8 is able to connect internet, and double-test through 3.5G network without company network policy.
请各位帮忙澄清我的应用程序或WNS的问题。
Would you guys please help to clarify the issue from my app or WNS.
