Push notifications not receiving on device

Question

I am using APNS service in my universal app (iPhone/iPad) and i am not geting notifications on device. Previously i was getting notifications perfectly but now a days with the same code at server side and client, it is not working. On server side notification status is delivered but i am not receiving it on my device.

I have checked most of the questions on stackoverflow but i was unable to find my question. one guy said that in development environment it may have delays, but my problem is that i am not receiving notifications at all.

Note: i am using sandbox environment not production.

Just in case you haven't found a solution yet, one additional thing you could check is if your device's date and time is properly set (in the OS). If your iPod, iPhone or iPad isn't set to the current date, we found that notifications are ignored silently. Of course, there are many other possible explanations as to why your service stopped working, but this is a simple thing to check when everything else appears to be fine.
