how to make client connect to ratchet on live server?

问题

I've googled about this for so many days and till now the client (browsers) cannot connect to the server.

But the server can run. I think its because its connected to itself(localhost).

I did find ratchet documentation which says:

If you want to open Ratchet up (not behind a proxy) set the third parameter of App to '0.0.0.0'.

http://socketo.me/docs/troubleshooting

so i tried this in my server.php file. (doesn't work)

$server = IoServer::factory(

        new HttpServer(
            new WsServer(
                new Chat()
            )
        ),

        8180,
        '0.0.0.0'

    );

Next i tried changing the app.php file which located here(doesn't work):

/vendor/cboden/ratchet/src/Ratchet/App.php


 public function __construct($httpHost = '0.0.0.0', $port = 8180, $address = '0.0.0.0', LoopInterface $loop = null) {......

Then,i tried changing the port to something else. again the server can run but the client cannot connect.

I referred all these:

Someone please help. All I want is for the client to be able to connect to the ratchet websocket which is running on the server.
