Fatao Error: ServerConnectionFailureException

[CoinStacker]

Hello sorry i know this will be a basic answer but i've been digging around online for hours and can't find anything to solve it.

I'm getting the follow error:

[17-May-2021 12:21:39 UTC] PHP Fatal error:  Uncaught ElephantIO\Exception\ServerConnectionFailureException: An error occurred while trying to establish a connection to the server in /Users/#/html/sockets/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php:187
Stack trace:
#0 /Users/#/html/sockets/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php(48): ElephantIO\Engine\SocketIO\Version1X->handshake()

#3 {main}
  thrown in /Users/#/html/sockets/vendor/wisembly/elephant.io/src/Engine/SocketIO/Version1X.php on line 187

(filepath removed for privacy)

I did search through existing issues and found something similar at the URL below but it didn't - to me atleast - provide a solution.

https://github.com/Wisembly/elephant.io/issues/179

the code im using to initialize is as follows:

include ("vendor/autoload.php");
use ElephantIO\Client;
use ElephantIO\Engine\SocketIO\Version2X;
$version = new Version2X("http://localhost:3001");
$client = new Client($version);
$client->initialize();
$client->emit("new_order", ["test"=>"test","test1"=>"test1"]);
$client->close();

Any help would be incredibly appreciated.

All the best, Coinstacker Team

Hey,

Just edited your message to have the proper coloration and stuff. :}

To go back onto your problem, which version of socket.io are you using ? As far as I know and can remember, I think this lib is compatible with Socket.io 0.X, 1.X, and 2.X. I know socket.io has released several more versions since then, so not sure if it's not a compatibility problem which is likely.

IIRC, I did a debug possibility (to have more details) if you catch the error. There is a method to have more information I think :

include ("vendor/autoload.php");
use ElephantIO\Client;
use ElephantIO\Engine\SocketIO\Version2X;

try {
	  $version = new Version2X("http://localhost:3001");
	  $client = new Client($version);
	  $client->initialize();
	  $client->emit("new_order", ["test"=>"test","test1"=>"test1"]);
	  $client->close();
} catch (ElephantIO\Exception\ServerConnectionFailureException $e) {
	echo $e->getErrorMessage();
}

You should have more details on what failed...
