Socketio on https using redis - node.js

Question

I have a webapplication on a bitnami lamp stack, the os is ubuntu and it uses Apache as a webserver.
The SSL Certificate is generated using Let's Encrypt. I can visit the site on http and https.
Furthermore I am using following stacks:
- nodejs
- socket.io
- redis
Sending notifications on my local machine work fine, the websocket works.
But on my production Server which runs on https it does not work. I Keep getting following error messages:
socket.io.js:2 GET https://mypage.com:3000/socket.io/?EIO=3&transport=polling&t=MNxGNEt
net::ERR_CONNECTION_TIMED_OUT
This is how my socket.js (Server) Looks like:
var app = require('http').createServer(handler);
var fs = require('fs');
var io = require('socket.io')(app);
var Redis = require('ioredis');
var redis = new Redis();
// class declaration
var Redis = require('ioredis');
function handler(req, res) {
res.writeHead(200);
res.end('');
}
io.on('connection', function(socket) {});
var redisUserSignedUp = new Redis();
redisUserSignedUp.subscribe('signed-up-channel');
redisUserSignedUp.on('message', function(channel, message) {
message = JSON.parse(message);
io.emit(channel + ':' + message.event, message.data);
});
// run server on port 3000
app.listen(3000, function () {
console.log('Server runs!');
});
In my production I currently am trying it like this:
var app = require('https').createServer({
key: fs.readFileSync('/opt/bitnami/apache2/conf/serverKey.pem'),
cert: fs.readFileSync('/opt/bitnami/apache2/conf/serverCrt.pem')
}, handler);
var fs = require('fs');
var io = require('socket.io')(app);
var Redis = require('ioredis');
var redis = new Redis();
// class declaration
var Redis = require('ioredis');
function handler(req, res) {
res.writeHead(200);
res.end('');
}
io.on('connection', function(socket) {});
var redisUserSignedUp = new Redis();
redisUserSignedUp.subscribe('signed-up-channel');
redisUserSignedUp.on('message', function(channel, message) {
message = JSON.parse(message);
io.emit(channel + ':' + message.event, message.data);
});
// run server on port 3000
app.listen(3000, function () {
console.log('Server runs!');
});
And I am trying to Access it like this:
var options = {
key: fs.readFileSync('/opt/bitnami/apache2/conf/serverKey.pem'),
cert: fs.readFileSync('/opt/bitnami/apache2/conf/serverCrt.pem'),
requestCert: true
}
var app = require('https').createServer(options, handler);
local:
const socket = io('http://myapp.test:3000'); // localhost dev Folder is mapped to this .test url
socket.on('signed-in-channel:App\\Events\\UserSignedIn', (data) => {
…
production:
var socket = io('mypage.com:3000', {secure: true});

You only create a http server but to connect with ssl you need a https server.
var options = {
key: fs.readFileSync('./file.pem'),
cert: fs.readFileSync('./file.crt')
};
var app = require('https').createServer(handler);
