title: port 443 not working on https node express
body: <p>I'm running a https example server on <code>node.js</code> with express.</p>
  <p>I have my certificates and I'm able to run it on port 3000 or 8443.
  But I have to put the port on the domain <em>mydomine.com:8443</em> and if I want to access the https without saying the port, that should be 443, but this port doesn't load.</p>
  <p>I even tried changing the ports on my router to point to a working port, such as ext443-&gt;in8443, but that didn't work either. <a href="https://i.stack.imgur.com/dzjc8.png" rel="nofollow noreferrer">(ports configuration)</a></p>
  <p>So I'm wondering if it's really 443 that I'm looking for?</p>
  <pre><code>var fs = require('fs');
  var http = require('http');
  var https = require('https');
  var privateKey  = fs.readFileSync(__dirname + 'ssl/privkey.pem', 'utf8');
  var certificate = fs.readFileSync(__dirname + 'ssl/fullchain.pem', 'utf8');
  
  var credentials = {key: privateKey, cert: certificate};
  var express = require('express');
  var app = express();
  
  var httpsServer = https.createServer(credentials, app);
  
  app.use(express.static('public')); 
  httpsServer.listen(8443);
  </code></pre>
  <p>i even trdied <em>mydomine.com:443</em> and doent work either</p>
