Not able to connect to server with IP address even on same same system
Could you please help me?  I try to connect this video app with IP address (localhost IP: 192.168.1.229)  it could not work  even on same system . but it works fine when i am using localhost in place of IP. i follow your README.md file and change all required as you suggested. please find below my changes in code:
1: change in server.php file
//set an array of origins allowed to connect to this server
$allowed_origins = ['localhost', '127.0.0.1','192.168.1.229'];
// Run the server application through the WebSocket protocol on port 8080
$app = new Ratchet\App('192.168.1.229', 9300, '0.0.0.0');//App(hostname, port, 'whoCanConnectIP', '')

2: Change in comm.js file 
const wsChat = new WebSocket("ws://192.1.168.229:9300/comm");

Even i change IP with 127.0.0.1 it not works. Please suggest how it works
