Use PHP Websocket Ratchet online

Question

I’m trying to use the Ratchet to create WebSockets in PHP on a site I own. When I did the tests (localhost) everything worked perfectly, but when I try to put online, it does not run the connection. Reading more on the subject, I saw that it would be necessary to change the ip to be the server one - or use the correct reference. Which led me to this final code:

var socket = new WebSocket('ws://meusite.com.br:8000');

But when I access the site, after a while, I get this message:

failed: Error in Connection establishment: net::ERR_CONNECTION_TIMED_OUT

The server file kept this code:

require __DIR__ .'/../vendor/autoload.php';

use Ratchet\Server\IoServer;
use Ratchet\http\HttpServer;
use Ratchet\WebSocket\WsServer;

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Chat()
        )
    ), 2000, '0.0.0.0'
);
$server->run();

I’m using composer also for package management Ratchet.

I don’t know what could be happening to not having the connection or what I missed, but this process is not working online, only at localhost.

Editing the question, and already adding the answer to the comment, I have access SSH yes, even when I try to start the script as done in localhost

php bin/server.php

The SSH presents the following error:

Fatal error: Class 'Ratchet http Httpserver' not found in /bin/server.php on line 10

Note: The final application will not be a chat, I’m doing so just by following a tutorial. The goal is that there is only the exchange of messages to inform that a new order has been made, or that a new service order has arrived, etc...

Change:

use Ratchet\http\HttpServer;

For:

use Ratchet\Http\HttpServer;

Because this occurs:

In Windows the files are case-insentive, when you run:

use Ratchet\http\HttpServer;

It usually finds this in Windows (see that Http begins with the letter H capitalized):

./src/Ratchet/Http/HttpServer.php

Already Like-Unix systems such as linux use the file system as case-sensitive, then at the time you use use Ratchet\http\HttpServer; he seeks this:

./src/Ratchet/http/HttpServer.php

But on the server the file is like this:

./src/Ratchet/Http/HttpServer.php

Are different.
