How to run NODE.JS (Socket.io) - CENTOS 7 with SSL domain? - node.js

Question

My socket.io project "xampp" works fine for localhost.
I have a Centos 7 (cPanel) server. I did everything when I threw files into my server. I wrote the command "nodemon server.js" and the server is running. But I am having SSL-related problems with Client.
My site has SSL. I'm using CloudFlare. For this reason, the client cannot communicate with the server.
My project is running when I disable SSL.
How does Socket.io work with SSL?
CLOUDFLARE:
CHROME CONSOLE LOG:
Client CODE:
var socket = io.connect('https://example.com:1347');
Server.js CODE
var server = require('https').createServer(),
io = require('socket.io')(server),
port = 1337;
server.listen(port);

Answer 1

Firstly if you use CloudFlare. You should know SSL Ports.
HTTPS ports supported by Cloudflare:
443 2053 2083 2087 2096 8443
Use whichever port is empty on your server. Recommended: (8443)
Connect to your server with PUTTY. Then locate the directory of the domain on your server. If you are using cpanel. Follow this road.
cd /home/domainname/public_html
You will come to the site's home directory.
Then you need to create the necessary files for SSL to the server. Enter the individual commands below.
openssl genrsa -out privatekey.pem 2048
openssl req -new -key privatekey.pem -out certrequest.csr
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem
Client CODE:
var socket = io.connect('https://example.com:8443', {secure: true});
Server.js CODE
var fs = require('fs');
var https = require('https');
var options = {
key: fs.readFileSync('privatekey.pem'),
cert: fs.readFileSync('certificate.pem')
};
var server = https.createServer(options);
var io = require('socket.io').listen(server);
var port = 8443; // Enter any of the cloudflare ports.
server.listen(port, function(){
console.log('listening : ' + port);
});
