When I test Push Notification with apn_development_cer, it works with the loaded app on the iPhone device from Xcode.

But, when i am downloading the same application from App Store or with the Ad Hoc Distribution on the same iPhone device from Xcode, it just stops sending Push Notification with apn_production_cer.

For the sandbox instance we are using gateway.sandbox.push.apple.com, port 2195 while for the production build we are using gateway.push.apple.com, port 2195. We have verified that the port 2195 is not blocked by the firewall.

Thanks in advance!
