APNS notifications are not received in device, but server gets success (200) when send to APNS

In my application, I'm using both APNS for push notifications. In my app, both tokens are generated properly and updated on my App's server. When sending an APNS push from my server, the push is successfully reached the APNS server, but can't deliver to the device, even though we are getting success from APNS Server.

we are getting 200 from APNS.

but the same thing If I am trying to use the "Push Hero" 3rd Party app, and I am getting notifications in the app also, with no any issue. but can't get it from my server.

I am using a .p8 file for push notifications in both the server and 3rd party apps.
