First of all make sure you install production APN certificates on your server, not development certificates.
After that make sure, you are sending the notification to right server URL
- Sandbox:
gateway.sandbox.push.apple.com, port2195. (for thedevelopment) - Production:
gateway.push.apple.com, port2195. (for the release)
Still you have the same problem, try this App. APN Tester
