Peerjs keeps loosing connection and user id is lost - webrtc

Question

I have made an application following a tutorial using peerjs. Everything seems to be working fine except when I make a connection for a video call where I am using peerjs. I have made my own peerjs server which I am running on localhost (right now for testing). Here is the code for the peer server:
const express = require('express');
const path = require('path');
const http = require('http');
const cors = require('cors');
const errorhandler = require('errorhandler');
var ExpressPeerServer = require('peer').ExpressPeerServer;
var options = {
debug: true,
key: 'copycat'
};
var app = express();
var server = http.createServer(app);
var port = process.env.PORT || '3001';
app.set('port', port);
app.use(cors());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/peerjs', ExpressPeerServer(server, options));
app.use(errorhandler());
process.on('uncaughtException', function(exc) {
console.error(exc);
});
server.listen(port);
As you can see I am running the app on port 3001. Now following is the script for peerjs connection for a video call:
// PeerJS
// Compatibility shim
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
// PeerJS object
var peer = new Peer(username + roomId, {
host: 'localhost',
path: '/peerjs',
port: 443,
secure: true,
key: 'copycat',
debug: true
});
peer.on('open', function () {
$('#my-id').text(peer.id);
});
// Receiving a call
peer.on('call', function (call) {
// Answer the call automatically (instead of prompting user) for demo purposes
call.answer(window.localStream);
step3(call);
});
peer.on('error', function (err) {
alert(err.message);
// Return to step 2 if error occurs
step2();
});
// Click handlers setup
$(function () {
$('#make-call').click(function () {
// Initiate a call!
var call = peer.call($('#callto-id').val(), window.localStream);
step3(call);
});
$('#end-call').click(function () {
window.existingCall.close();
step2();
});
step1();
});
function step1() {
// Get audio/video stream
navigator.getUserMedia({ audio: true, video: true }, function (stream) {
// Set your video displays
$('#my-video').prop('src', URL.createObjectURL(stream));
window.localStream = stream;
step2();
}, function () { $('#step1-error').show(); });
}
function step2() {
$('#step1, #step3').hide();
$('#step2').show();
}
function step3(call) {
// Hang up on an existing call if present
if (window.existingCall) {
window.existingCall.close();
}
// Wait for stream on the call, then set peer video display
call.on('stream', function (stream) {
$('#second-video').prop('src', URL.createObjectURL(stream));
});
// UI stuff
window.existingCall = call;
$('#second-id').text(call.peer);
call.on('close', step2);
$('#step1, #step2').hide();
$('#step3').show();
}
This is pretty much the example code from peerjs example file on github. What I am confused about is the port value. Inside the options in the above script its port 443. I get the following error in chrome when I try to make a video call:
peer.js:1492 WebSocket connection to 'wss://localhost/peerjs/peerjs?key=peerjs&id=User80925be509c6c606fa21409858f5&token=zz69b3ccyk' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

Please advise what am I doing wrong???

If you are using at your local end then use your localport i.e. 3001 else use 443
make object like this
var peer = new Peer(undefined, {
host: 'localhost',
path: '/peerjs',
port: 3001,
secure: true,
key: 'copycat',
debug: true
});
