Port 2195 open but cannot access APNS server - php

Problem:
I cannot access APNS server. I get a 110 Connection Time Out error.
My situation:
I've contacted my host (hostmonster). They said my port 2195,2196 are already open.
My certificate and passphrase is no problem, for I've tested it from my local Mac.
I use a very simple PHP to test. Here's my code:
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'apn.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', 'aaa');
$fp = stream_socket_client("ssl://gateway.sandbox.push.apple.com:2195", $err,
$errstr,60,STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT,$ctx);
if ($fp)
echo ('aa');
else
echo ($err.$errstr);

I had the same exact problem, but with Bluehost. In my case, it turned out the Bluehost firewall was not properly open. The first line chat support from Bluehost said the ports 2195 & 2196 are open, and the problem was not with them. To demonstrate the problem was on their side, I asked them to run the following telnet command from the Bluehost server:
telnet gateway.push.apple.com 2195
Trying 17.149.36.246...
Trying 17.149.35.166...
Trying 17.149.35.170...
Trying 17.149.35.177...
... Connection timed out
The output should be:
telnet gateway.push.apple.com 2195
Trying 17.149.36.230...
Connected to gateway.push.apple.com.
Escape character is '^]'.
Then i submitted a support ticket to Bluehost with this information. They resolved the issue in 6 hours by properly opening the firewall.

Send push notification to ios app : Google cloud

I have hosted my PHP code on google cloud.
I want to send push notifications to ios app. I have enabled port 2195 and 2196.
While sending the push notification I got the following error :
Warning: stream_socket_client(): SSL: Connection reset by peer
Warning: stream_socket_client(): Failed to enable crypto
Warning: stream_socket_client(): unable to connect to
ssl://gateway.push.apple.com:2195 (Unknown error)
I am not much familiar with Google Cloud. What should I do to make it working?
Here is code:
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', PEM_FILE_PATH . 'apns-dev.pem');
$fp = stream_socket_client("ssl://gateway.push.apple.com:2195", $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
if (!$fp) {
$data['msgs'] = "Failed to connect $err $errstr \n";
} else {
$payload = json_encode($body);
$msg = chr(0) . pack("n", 32) . pack("H*", str_replace(" ", "", $deviceToken)) . pack("n", strlen($payload)) . $payload;
$result = fwrite($fp, $msg);
if (!$result) {
$data['msgs'] = 'Message not delivered'; //. PHP_EOL;
} else {
$data['msgs'] = 'Success'; //. PHP_EOL;
}
fclose($fp);
}
return $data;
The main problem when we are trying to send data to the APNS (Apple Push Notification Service) servers is the SSL certificates.
APNS uses this technology in order to serve more secure connection to its users.
As it is said at APNS documentation: "Each certificate is limited to a single app and is also limited to one of two development environments, each with its own assigned hostname". So you can use two environments
Development (testing environment): ssl://gateway.sandbox.push.apple.com:2195
Production (once the app is launched): ssl://gateway.push.apple.com:2195
If you want to test if you can connect to APNS server, just try the following command:
$ telnet gateway.sandbox.push.apple.com 2195
Trying 17.172.232.226...
Connected to gateway.sandbox.push-apple.com.akadns.net.
Escape character is '^]'.
If you get an error then make sure your firewall allows outgoing connections on port 2195.
Then you can test if your SSL certificate and private key are working and it can be set up a secure connection:
$ openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert YourDevCert.pem -key YourPrivateKey.pem
Enter pass phrase for YourPrivateKey.pem: ******
If this works it means that your certificates are correctly set up (you should see a whole bunch of output, which is openssl letting you know what is going on under the hood).
Once knowing all of this information, I see that you have one mistake in your code and also you should check something else:
Check if you have a good connection with APNS server.
Check that your $payload variable is a json string.
Check that you have a correct $deviceToken.
Check that you are using the right certificate with the right environtment. In this case, you are setting a apns-dev.pem certificate and you are sending it to the production environment (I interpret that your production certificate is apns-prod.pem so check it).
Check that your PHP file can find your certificate.
One of your problems, you haven't set any password for your private key. You should add the following line once you have added your certificate:
stream_context_set_option($ctx, "ssl", "passphrase", "your_private_key");
If you have some troubles or doubts, I followed this tutorial to send my first APNS Push Notifications.

Correct way to reopen TCP connection with PHP after remote party closes?

I'm having issues reopening a TCP socket connection after its remotely closed. Specifically this is for Apple Push Notification service - when Apple encounters a device token from you that pairs with a device that deleted your application they close the secure TCP socket to their push gateway. I need to immediately reopen this connection (or start a new one) when this issue occurs so I can continue sending notification to other users who still do have the app installed. I have some code using which I try to sort this out but it's freezing my entire Apache server and I have to restart manually to get things running again and I have no idea why. Below is the code with which I attempt to reopen a socket with Apple:
if($error_response == "InvalidToken"){
$results .= "\ntried to restart";
fclose($fp);
usleep(20000);
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck_real.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', '****');
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
}

Unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection refused)

I have a problem, I'd like to send out push notifications using php, however I keep getting this error:
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection refused) in /home/colupon/public_html/iPhone/push/index.php on line 21
Failed to connect: 111 Connection refused
My code is as follows:
$deviceToken = '0f************************************************************78';
$passphrase = '************';
$message = 'My first push notification!';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
$filename = 'ckdev.pem';
stream_context_set_option($ctx, 'ssl', 'local_cert', $filename);
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
echo 'Connected to APNS' . PHP_EOL;
// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default'
);
// Encode the payload as JSON
$payload = json_encode($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));
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered'.PHP_EOL;
// Close the connection to the server
fclose($fp);
?>
I believe the problem is with the server I'm using because I posted the same code and the same .pem file on a different server and it sent the notification without any problem. I attempted to open up ports on the firewall for my server because I read that might cause this problem, but the same error message still showed up. Is there anything else I can do? Any help would be greatly appreciated, thanks!
This issue is common problem in Apple Push notification, to resolve this error you have to go through as follows:
Test your pem files locally and remotely in server if the problem is server go to 2 else build pem correct file.
Set up the permission wrong on the folder that had the certificate file. This worked for me:
chmod 755 your_folder_that_has_certificate_files
3.Check connectivity of apns port 2195 from your hosting server as follows:
run
telnet gateway.push.apple.com 2195
if this is the problem
Trying 17.172.233.36...
telnet: connect to address 17.172.233.36: Connection refused
you can solve this issue by opening the port 2195 on the production server. You can verify by following command $telnet gateway.push.apple.com 2195
-bash-3.2# telnet gateway.push.apple.com 2195
Trying 17.149.38.141...
Connected to gateway.push.apple.com (17.149.38.141).
Escape character is '^]'.
Connection closed by foreign host.
In case of MAC,
(built-in server was working fine using terminal but not through browser, for me, so i installed MAMP.)
1.Go to---> /Library/WebServer/Documents/----copy both php and ckdev.pem file here.
2 go to terminal-->$open /private/etc-->go to--->apache2>originals>httpd.config file-->
**"#LoadModule php5_module libexec/apache2/libphp5.so", remove "#"..(perhaps, you would have to change the permission also..!)
then goto browser and check--> localhost/yourPhpFile.php
In Case of Windows system,
1.Install WAMP,
2.goto php.ini file--->search for this ";extension=php_openssl.dll" line and remove semicolon ";".
3.click WAMP icon from right-bottom goto PHP>PHP Extensions>select php_openssl..
That's it..hope this may help further seekers.
In my case the problem was that I forgot to setup my passphrase correctly in php script.
<?php
// Put your device token here (without spaces):
$deviceToken = 'xxx';
// Put your private key's passphrase here:
$passphrase = 'xxx';
To me, it was the SELinux issue.
So in your /etc/selinux/config file, set the SELINUX=enforcing to SELINUX=disabled. And restart. Thats it.
I just had the SAME error and I found the solution for my problem.
‚mypassword‘ instead of 'mypassword'
Seems like notepad changed the quotes. This literally took me 4 hours... Hopefully someone will read this and save some time...

Apple Push with proxy and stream_context

I have to send push notification to iOS devices. My connection has to be enabled through a proxy. I tried everything but without success. I have an error 110 Connection Timed Out. It's working with cURL if I just try to connect to Apple push's address. I don't know where the problem is. Proxy config ? PHP stream_context wrong implementation ?
Here's my code :
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'certificate.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', 'my_passphrase');
stream_context_set_option($ctx, 'ssl', 'verify_peer', false);
stream_context_set_option($ctx, 'http', 'proxy', 'tcp://my-proxy.net:8080');
stream_context_set_option($ctx, 'http', 'request_fulluri', true);
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err,$errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
var_dump($fp);
var_dump($err);
var_dump($errstr);
exit;
Do you have an idea ?
EDIT:
Can it be directly linked to Squid ? I just figured out the proxy is running with Squid.
I also try with fopen() function instead of stream_socket_client() but it seems it doesn't allow ssl protocol.
Here's my var_dump outputs : bool(false) int(110) string(20) "Connection timed out"
I also have this warning : Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection timed out) in /share/www/website/test.php on line 22
It could simply be your proxy does not allow port 2195 to be opened.
iPhone Push Notification Unable to Connect to the SSL Server
I guess you either:
Need to talk to the people who run the proxy to see if port 2195 is open or not.
or
Setup a test server listening on port 2195 and then try to do a test connection to it through the proxy. That should allow you to test if it is the proxy that is blocking the connection requests.
or
Test whether Curl can open the connection using a proxy.
Which is done by setting the options:
// sets the proxy to go through
curl_setopt($ch, CURLOPT_PROXY, $proxy);
// sets to use a tunnel proxy which most http proxies are
curl_setopt($ch, CURLOPT_HTTPTUNNELPROXY, $proxy);
Full testing code here.
create the SSL context
open a tcp socket to the proxy
send request to the proxy to connect to APNs
once connexion is accepted enable SSL
Have a look at my reply in this post: Send Push Notification to APNS through proxy

stream_socket_client unable to connect (connection timed out)

I am using the certificate, and the private key
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', $certfile);
stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);
$fp = stream_socket_client('ssl://gateway.xyz.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
Its running in my local XAMPP Server, but its not working in the external server:
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Connection timed out) in /home/biranchi/public_html/push.php on line 42
Failed to connect 110
What is the error? Do i need to change some setting in the server?
I had fixed the issue by opening the port 2195 on the production server. You can verify by following command $telnet gateway.push.apple.com 2195
-bash-3.2# telnet gateway.push.apple.com 2195
Trying 17.149.38.141...
Connected to gateway.push.apple.com (17.149.38.141).
Escape character is '^]'.
Connection closed by foreign host.
Check your personal firewall settings and make sure you're not blocking this out. Try disabling the firewall.
Also, some APIs like requests to come from an actual domain rather than a desktop. I don't have reason to believe Apple works this way, but that's something to check also.
Also make sure and ping gateway.sandbox.push.apple.com and make sure you have a good connection.
You have to set your firewall to allow all the 17.0.0.0/8 block (it all belongs to Apple!). Check THIS ANSWER
And according to Apple:
The APNs servers use load balancing, so your devices won't always connect to the same public IP address for notifications. It's best to allow access to these ports on the entire 17.0.0.0/8 address block, which is assigned to Apple.
If you are using CSF firewall (like me), I'd recommend to add this line to csf.allow file:
tcp|out|d=2195|d=17.0.0.0/8
Then restart CSF. Using the above instead of just "17.0.0.0/8" will allow only outbond connections to Apple and specifically to port 2195. NSA won't like it but this is much more precise and safe! ;)
