WebSocket connection to failed: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT

After checking your app page source i found that you are using localhost for connection on line number: 38

var conn = new WebSocket('wss://localhost:8080');

Which is wrong, you should use your own domain name.

Second thing is after checking port forwarding on you domain i have found that port 8080 is blocked right now. So you should better ask your hosting provider to open port in IPTABLES for incoming connections or if you have root access then try this Article it might help you to allow port forwading.
