Push notifications (iPhone) give "111 Connection refused" - php

Question

When I try to send Push Notifications I get this error: "Connection refused", but I don't know why... I've uploaded my apns-dev.pem in the same directory as well in the root-directory but that won't work either.
<?php
$payload['aps'] = array('alert' => 'This is the alert text', 'badge' => 1, 'sound' => 'default');
$payload = json_encode($payload);
$apnsHost = 'gateway.sandbox.push.apple.com';
$apnsPort = 2195;
$apnsCert = 'apns-dev.pem';
$apnsPass = 'secret';
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
stream_context_set_option($streamContext, 'ssl', 'passphrase', $apnsPass);
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 60, STREAM_CLIENT_CONNECT, $streamContext);
if (!$apns) {
echo "Error: $errorString ($error)";
}
// Do this for each
$deviceToken = '00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000';
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
fwrite($apns, $apnsMessage);
// End do
socket_close($apns);
fclose($apns);
?>
Does anyone know what I'm doing wrong? When I remove the passphrase and don't send it it doesn't work either...

Answer 1

Make sure the outgoing port 2195 is open.This would be in your firewall config.

Answer 2

You don't want a passphrase unless your .pem file requires one. The connection requires peer verification (option verify_peer) turned on. Also, make sure $apnsCert is the valid path to the certificate, you can use an absolute path as a sanity check.
Lastly, this shouldn't effect your ability to connect, but your device token needs to be valid.

Answer 3

I've know fixed that error by adding this: STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT
Know I'm not getting any errors, but I don't receive any notification. I think the Dev-token is not valid know, so, this is how it look like
numbers numbers numbers numbers numbers numbers numbers numbers.
The spaces are removed in this line:
$apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;
Edit: I founded the problem:
My server is refusing the outgoing port, just sent a mail, hoping they can activate it...
