Network Connection Issue
Hi, 

I'm experimenting some trouble when establishing the WebSocket Connection through the network, while  when setting it up locally it works perfectly.

It's extrange because the connection gets established but then an error appears and closes it.

I got the following error:

Here is line 31 of AbstractConnectionDecorator

ChatController is a variable I create to control the data recieved with onMessage and works perfectly in localhost.

My server code looks like:

``` php
  $server = IoServer::factory(
        new WsServer(
            new Chat($servidorWS,$token)

        )
      , 8080, '0.0.0.0'
    );
    echo 'Running';
    $server->run();
```

I'll appreciate any help. Thanks in advance
