My express server says that ports 80 and 443 are in use, but `netstat -nlp` says otherwise

Question

I try to run my Express server on ports 80 and 443, but I'm getting an error that they are already being used.

EADDRINUSE err

However, my Ubuntu server says that in fact ports 80 and 443 aren't busy:

ubuntu@ip-182-47-78-432:~$ sudo netstat -nlp

I get:

What can be happening? Or what other command can I run to find something useful?

Edit 1:

My code:

var fs = require('fs');
var http = require('http');
var https = require('https');
var app = require('./app');

var credentials = {
    key: fs.readFileSync('private_key.pem', 'utf8'),
    cert: fs.readFileSync('com_certificate.pem', 'utf8'),
    ca: [
        fs.readFileSync('com_certificate_chain_1.pem', 'utf8'),
        fs.readFileSync('com_certificate_chain_2.pem', 'utf8')
    ]
};

http.createServer(app).listen(80, function() {
    console.log('HTTP server started on port ' + 80 + '...');   
});

https.createServer(credentials, app).listen(443, function() {
    console.log('HTTPS server started on port ' + 443 + '...');
});

I'm on an Amazon cloud server, it doesn't have a Skype running.

Edit 4:

The error message I get when trying to run the server:

ubuntu@ip-172-31-15-213:~/services/api$ nodemon server.js

Looks like I got a different error this time though...

Edit 5:

If I run telnet localhost 80, I get:

ubuntu@ip-172-31-15-213:~/services/api$ telnet localhost 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

I just posted it. I don't think my code is wrong though. It's probably something using those ports that I'm unaware of. — bmpasini, Apr 17 '15 at 05:29
post the code in app.js. I bet it's also calling `createServer`. blaming Amazon isn't going to get you anywhere. — Travis Webb, Apr 17 '15 at 05:30
it says both 80 and 443 are in use, not just one of them? can you post the full error message? — Travis Webb, Apr 17 '15 at 05:35
If I try to run only each of them at a time I still get the same errors. So, I suppose both are in use. — bmpasini, Apr 17 '15 at 05:36
You do `telnet localhost 80`, let's see if it is connecting to any running service. — NarendraSoni, Apr 17 '15 at 07:23

Your error says Error: listen EACCES, not EADDRINUSE.

The reason for the EACCES is that binding to ports below 1024 (like 80 and 443) requires root privileges, and you don't seem to be starting your app as root (before doing that, please make sure you know the implications of running apps as the root user).

If you are using skype

try disabling it to use port 80 for connections

Open Skype if it has not already been launched
Go to Tools –> Options from the dropdown menu
Select “Advanced” in the left-hand column, last option
Select “Connection”
Deselect the option that says, “Use port 80 and 443 as alternatives for incoming     connections”
Click Save
Exit and then restart Skype

here is the link

what does skype have to do with this? – Travis Webb Apr 17 '15 at 05:31
@TravisWebb "it says both 80 and 443 are in use," one of the possible reasons is skype. I have clearly written "If you are using skype". – Rohit Rehan Apr 17 '15 at 06:08

If you are using BonziBuddy or Limewire, it could be some other problem. Who cares? The answer isn't relevant, it's a random stab in the dark. – Travis Webb Apr 17 '15 at 14:00

My express server says that ports 80 and 443 are in use, but `netstat -nlp` says otherwise
