MPNS messages are not working

Question

I have made a windows phone 8.1 application using cordova(Phonegap). I am using PushPlugin for notification. It works perfectly fine for Android and iOS, but for Windows phone 8.1 it doesn't work. Actually it works randomly.

I am using Toast notification for windows. So some times I receive toast notification; some times I don't.

I am successfully generating channel and registering at MPNS. Notification URI is something like given below.

• CASE I.

  Server side implementation is in PHP. When I receive Toast Notification on windows device, response at server is

  [HTTP/1.1 200 OK
  Cache-Control: private
  Server: Microsoft-IIS/8.0
  X-Server: RD000D3A107A1E
  X-DeviceConnectionStatus: Connected
  X-NotificationStatus: Received
  X-SubscriptionStatus: Active
  X-MessageID: 00000000-0000-0000-0000-000000000000
  X-AspNet-Version: 4.0.30319

• CASE II.

  But when I don't receive a Toast notification, response at server is

  Blank Array( [] )
  

  I am wondering why response is blank array instead of any proper response as described above.

I have tried both cases with Wifi and Data Connection, but result is the same.
