I am integrating an IP-Restricted API from a company called XendPay. They allowed requests from the Server IP only. I know PHP scripts run on server but I am not getting response when I request data.
Here is an example:
$jsonRequestURL = 'http://uat.xendpay.com/partner/api/1.0/{partner_key}/quote?countryFrom=PL&countryTo=GB¤cyFrom=PLN¤cyTo=GBP&deliveryType=BANK_TRANSFER&paymentMethod=banktransferlocal&amount=1000.00&amountCurrency=PLN&indent=true';
json_decode ( file_get_contents ( $jsonRequestURL ) );
It sometimes stuck here or after waiting quite long, gives the following error:
A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection
failed because connected host has failed to respond.
I am not sure but I assume that request is not being sent through Server IP as I have called above mentioned json_decode() on pageload.
Can anyone suggest what should I do?

After reading the following links:
get url content PHP
file_get_contents failed to open stream: Connection refused godaddy server with remote connection server
PHP file_get_contents() returns "failed to open stream: HTTP request failed!"
I'm having a problem with the function file_get_contents or even curl in one of my servers at hostgator, they are not working, returning the PHP error failed to open stream: Connection refused. I've tried cURL with USERAGENT set with no result too. It's a simple weather service that I'm creating, it returns the altitude, wind direction, speed and temperature on a certain coordinate of the globe.
Return sample: 30000;221;2;-32;1;
In the other side (request side), I have a web server running IIS 7.5, with all router firewalls, computers firewalls and antivirus softwares disabled only for testing, and is still refusing the connection ONLY for the hostgator servers. I've tried the same code in other web hosting providers, and the code is working properly.
This service will handle a lot of requests per minute, and this seems to me that something has blocked my connection between hostgator and my server due to the number of requests. But I don't know where!!
The page is perfectly accesible via browser.
This is my enviorioment at the hostgator side:
allow_url_fopen: On
allow_url_include: On
OpenSSL: Enabled
Here is my PHP code:
$datalink = "http://#####.########.###:8280/weather.php?waypoint_lat=-10.981925&waypoint_lon=-37.077377&altitude=30000";
$weather_layer = file_get_contents($datalink);
echo "Layer ($datalink):" .$weather_layer."<br>";
Isn't Hostgator blocking the requests because of the DDoS protection? Give them a call, my hosting provider was blocking connections to my other server because they were thinking it was some hacker DDoSing using my hosting.
Also, there might be problem with the port in URL - Hostgator cannot proccess it?

I was getting the same error in phperror.log which I have configured in my php.ini. Initially I thought it was due to some firewall issue, but it wasn't.
The problem was, I was running the client first and then the server. Client was probably not able to make a connection with the server when it ran for the first time.
So I resolved it by running the server first and then the client, which can now make a successful web socket connection.
EDIT : This error also comes up when we simply reload the client page without properly terminating the previous connection.
I'm trying to use the http://ip-api.com/json/ api for get and show the information of a visitant that conects to my website on hostinguer.com.
When I do the next, it should responds me with a json with all the info in a json format:
echo file_get_contents("http://ip-api.com/json/{$user_ip}");
But I get the following error message:
Warning: file_get_contents(http://ip-api.com/json/[MY PUBLIC IP]): failed to open stream: Connection refused in /home/[HOSTINGUER USER]/public_html/ip2.php on line 31
And other strange thing: if I use another API it works correctly and returns me the correct Json! The other API command:
echo file_get_contents("http://ipinfo.io/{$user_ip}/json");
So, I want to use the ip-api.com API cause the results are more accurate, but only works if I use ipinfo.io API... Why can I do the petition to a website and not to the other?
Otherwhise, I tried both in local using curl or writting in my webrowser and it works correctly. Also I tried in local in a Lammp and the both works perfectly. And finally I tried somthing like this post: PHP file_get_contents() returns "failed to open stream: HTTP request failed!" in hostinguer and it doesn't works..
I thought maybe is something in the hostinguer configuration but...
Thanks in advance!
Your IP address is banned. If you're using normal web hosting, your outgoing IP address is shared with other users, who probably did more requests than allowed.
Go to http://ip-api.com/docs/unban and enter your server's outgoing IP address (check it via http://ipinfo.io/json)
I have a PHP server-like script that runs indefinitely. It connects to APNS (Apple Push Notification Service) with a stream_socket_client object in PHP.
The problem is that while this works most of the time, I cannot figure out how to validate if the connection to APNS is available when I want to send a push notification. The script receives incoming connections and copies the content to APNS.
When it doesn't work, the script reconnects (the return value of stream_copy_to_stream is 0 on 0 bytes written, which triggers reconnect) and then the next incoming token will succeed, but it logs the following and of course does not deliver the message:
PHP Warning: stream_copy_to_stream(): SSL: An established connection was
aborted by the software in your host machine.
Is there any way to detect the above and thus reconnect to APNS before trying to write to the socket.
And doing this before trying to copy to APNS:
if (!$socketObject) {
// reconnect
}
Does not work, as the object still exists (var_dump will print a description). So how can I check if the connection is still open?
Writing anything to the socket that is not a valid token and payload will cause APNS to disconnect.
The code that performs the writing looks like this:
function writeToAPNS($client) {
return stream_copy_to_stream ( $client, $this->connectionAPNS );
}
Where $client is returned from stream_socket_accept ( $this->socket, -1 ) and $this->socket is a variable containing the local socket object listening for incoming connections. -1 means there is no timeout when waiting for an incoming connection. When it works this function returns the number of bytes written. When it fails it returns 0.
$this->connectionAPNS is the object returned from stream_socket_client when connecting to APNS. This is what I want to check for validity before I perform the stream_copy_to_stream function.
So basically I want to detect if $this->connectionAPNS is valid.
I tried dumping the metadata for the connection object, but it doesn't say anything about the validity, only if it's timed out, protocol type etc.
Did you see this note in the official stream_socket_client documentation?
UDP sockets will sometimes appear to have opened without an error, even if the remote host is unreachable. The error will only become apparent when you read or write data to/from the socket. The reason for this is because UDP is a "connectionless" protocol, which means that the operating system does not try to establish a link for the socket until it actually needs to send or receive data.
Please try this methiod stream_get_meta_data on your connection to try to detect a difference. I can't test it right now, but it might help you. Especially the timed_out property.
Another option to at least mute the error messages, since you are handling them, is to set an appropriate errno on the stream_socket_client.
Well, as explained by M.K., this is how UDP works. And by the way, your code works. Your problem is the warning, which is fairly easy to get rid of by adding an # to your write function.
Your code would then look like :
function writeToAPNS($client) {
return #stream_copy_to_stream ( $client, $this->connectionAPNS );
}
I'm having trouble with using APNS with PHP and getting the following message:
stream_socket_client(): Failed to enable crypto
The problem only happens sometimes, and other times it would actually send the push.
Since I have the test script on a loop of 10 iterations, I would sometimes get this:
stream_socket_client(): SSL: Connection reset by peer
I'm testing using the sandbox server tls://gateway.sandbox.push.apple.com:2195
Here is what I tried:
I tried to reissue the PEM and all certificates with it.
I played around with the request protocol sslv3:// and tls://.
I played around with the passphrase (push worked without the passphrase btw)
I tried searching stackoverflow for a solution and nothing worked.
Checked pem file permissions 644
Checked pem parent directories permissions 755
It seems that all the solutions I found on Google and SO are people having problem pushing altogether.
I feel like the service is rate limited maybe? Because we waited a while (around 15 minutes) and then tried it again, and was able to successfully push around 100 messages until I started getting that message again.
The sandbox push service is rate limited. I have experienced this myself when testing but have never encountered any such limit using the production API.
You might also be hitting their other protections.
Are you opening a connection, sending a message, closing connection and then looping and doing it all over again?
That will get your notifications dropped. Apple wants you to send several push notifications using the same connection, not a new one each time.
Best Practices for Managing Connections
You may establish multiple connections to the same gateway or to
multiple gateway instances. If you need to send a large number of
remote notifications, spread them out over connections to several
different gateways. This improves performance compared to using a
single connection: it lets you send the remote notifications faster,
and it lets APNs deliver them faster.
Keep your connections with APNs open across multiple notifications;
don’t repeatedly open and close connections. APNs treats rapid
connection and disconnection as a denial-of-service attack. You should
leave a connection open unless you know it will be idle for an
extended period of time—for example, if you only send notifications to
your users once a day it is ok to use a new connection each day.

My PHP code was generating following error:
PHP Warning: stream_socket_client(): Failed to enable crypto in /private/tmp/t.php on line 12
PHP Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in /private/tmp/t.php on line 12
PHP Warning: fclose() expects parameter 1 to be resource, boolean given in /private/tmp/t.php on line 24
The problem was, the damn certificate, expired the day before yesterday! :-) Can you believe this?
So, I need to recreate my PEM file.
It is not necessary recreate your pem file
that error happens when you use an incorrect PassPhrase

I had this problem. Disappeared after giving write permission for 'everyone' for the .pem file.
I have this problem because I foolishly forgot to include the file extension (.pem) when supplying the file path for local_cert.
few checks :
device token should be - with out spaces and with out < or >
make sure the path of certificate is correct and expired date of it.
make sure the passphrase you are using is the one u used to make certificate
In my case, the issue was with my mac (OSX Sierra). I uploaded php and cert to my server, ran it, and the notification was delivered.
I tried examples from book of Marin Todorov iOs 6 by Tutorials.
And before I could send push notifications for automatical update I had a lot of headache cause of handshake error - stream_socket_client(): Failed to enable crypto.
I did all of what I found in Stackoverflow - changed permissions on certificate and others.
What I did eventually?
I created selfsigned SSL certificate and setup Apache for serving SSL.
Also I changed SSL protocol from ssl to tls in hostname:
tls://gateway.push.apple.com:2195
After that service works.
