Warning: stream_socket_client(): unable to connect to ssl://gateway.push.apple.com:2195 (Connection timed out)

When I try to make a push from my local server, it is working fine. But when I am trying the same from external server, I am getting the warning. I am using php and apache.

"Warning: stream_socket_client(): unable to connect to ssl://gateway.push.apple.com:2195 (Connection timed out)".

Below are the configuration in my apache server.The same is iin my local server.But I can not understand why it is always showing me the warning for external server.

Below are my code in php

ini_set("max_execution_time","6000");

//ini_set("max_input_time","1000");

ini_set("default_socket_timeout", 6000);

get_device_token();

function get_device_token(){

$_GET['token'] = 'cc706d069568493f6504186ec5784435284f3625fdba2f69f698a00f9d1526fb'; //Namrata's device old

if(!empty($_GET['token'])){

$deviceToken = $_GET['token'];

//$deviceToken = 'ebf46d5cc1b2f7c34b5a53c1c64c09fbd2e6af8ecffa665a6453e72b24315e0d'; // Namrata's device new

//echo $deviceToken;

$message = "This is new push test-from local";

$res=send_ios_notification($deviceToken, $message);

echo $res;

}else{

echo "No device token";

exit;

}

var_dump( $fp );

if (!$fp)

exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body

$body['aps'] = array(

'badge' => +1,

'alert' => $message,

'sound' => 'default'

);

$payload = json_encode($body);

// Build the binary notification

$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server

$result = fwrite($fp, $msg, strlen($msg));

var_dump( $result );

//print_r( $result );die;

fclose($fp);

die("end");

return $result;

}

Please suggest some solutions.I badly need it.
