Common issues

Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to

ssl://gateway.push.apple.com:2195 (Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?)

Soln: Check whether OpenSSL is enabled if not kindly enable.

Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to

ssl://gateway.sandbox.push.apple.com

Warning: stream_socket_client() [function.stream-socket-client]: failed to create an SSL handle

Soln:

Increase your timeout (4th argument of stream_socket_client()) and make sure that you have outgoing port 2195 open in your production environment.

This can be tested by executing following from your terminal

-bash-3.2# telnet gateway.push.apple.com 2195
