Apple Push Notification Service - notification messages aren't sent to iphone device

Question

Hi all,

I constructed provider code with using C# and it was able to send notification messages to iphone devices successfully. But since yesterday, it hasn't worked. Also it seems to connect APNS successfully and send notification message. Unfortunately, no notification message is received by iphone device. I controlled internet connection and device token of iphone device. What else can I do? Thanks in advance...

I dont have enough rep to comment on the question so typing out answer - Please add more details and I will edit my answer.

Is this in a developer / testing environment and are you using an ad hoc profile to install the application on the iphone devices? Did you check if the device token has changed and that you are using the new/ correct token in the C# code?

Do provide more details of your problem.
