I tried to create the file. pem several times but never goes well.

For generating the pem file I performed the steps as described on Apple Documentation.

What is the matter?

Answer 1

Did you check that your server can access to apple servers ?

Try with telnet:

telnet gateway.sandbox.push.apple.com 2195

If the answer is yes, my advice is to follow that tutorial to be sure that your pem file is well generated: http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1 (Go to "Making a PEM File" chapter)
