I can't start connection with WebSockets in EC2

I really need help with websockets, recently I used SSL(Let’s Encrypt) in my website that is in ec2, and I used route 53 for routing, and the website works perfectly with SSL and my DNS, but I can’t start connection with WebSockets and HTTPS, it only works with HTTP, using the port 8080, when I try to start connection with HTTPS under port 8443, Google console says:

WebSocket connection to "mysite" failed: WebSocket opening handshake
timed out

I really don’t know what to do anymore, in my point of view everything is okay with the part of coding but it really looks like a problem involving Apache and SSL, please help me, I’m with this problem there are 2 weeks and I don’t know what to do

AWS:

PHP:

<?php
use RatchetServerIoServer;
use RatchetHttpHttpServer;
use RatchetWebSocketWsServer;
use AnneSocketChat;

    require dirname(__DIR__) . '/vendor/autoload.php';

    $server = IoServer::factory(
        new HttpServer(
            new WsServer(
                new Chat()
            )
         ),
        8433
    );

    $server->run();

JS:

var conn = new WebSocket('wss://example.com:8433/chat.php'); //Using port 8433, it doesn't works as any port, I already tried a lot of ports

Apache
