Why doesn't Push Notification work on production?

Question

Objective-C

1. AppId contains 2 certificates for push notifications (development and production respectively)
   
   
2. Certificates and .pem files were created according to the manual
   
3. Development-Push sent through gateway.sandbox.push.apple.com:2195 come out wow.
   
4. Production-Push sent via gateway.push.apple.com:2195 sent but not received

5. I tested both with the application downloaded from the AppStore and with the Ad-hoc assembly. On different devices.
   
6. PHP is running on the server
   

It is noticed that during generation of .pem file there is no difference between prod.pem and dev.pem. Which is suspicious. Although the files prod.p12 and dev.p12, from which they are obtained, are different.
Maybe I'm generating prod.pem somehow wrong? I will be glad to any thoughts.

Answer 1

Prod.pem generated differently from this manual
openssl x509 -in aps_production.cer -inform der -out PushChatCert.pem
openssl pkcs12 -nocerts -nodes -clcerts -out PushChatKey.pem -in PushChatKey.p12
cat PushChatCert.pem PushChatKey.pem > production.pem
And voila!
