端口 443 在 https node express 上不工作

Question

I'm running a https example server on node.js with express.

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 mydomine.com:8443 and if I want to access the https without saying the port, that should be 443, but this port doesn't load.

I even tried changing the ports on my router to point to a working port, such as ext443->in8443, but that didn't work either. (ports configuration)

So I'm wondering if it's really 443 that I'm looking for?

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);

i even trdied mydomine.com:443 and doent work either

443 requires sudo on linux, and admin permissions on Windows, because it's reserved. You can run this program as sudo.
