nodejs & express https server with NGINX - node.js

Question

I'm trying to setup a nodejs server with https to make REST calls to.
Connecting directly to ip + port through http works fine. When using https with ip and port my android app complains that "the Hostname xx.xx.xx.xx not verified". So I figured I should setup a domain for it to make my certificate match.
With NGINX I made the following:
server {
listen 80;
server_name rest-ssl.mydomain.com;
location / {
proxy_pass https://xx.xx.xx.xx:4443;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffering off;
}
}
server {
listen 80;
server_name rest-normal.mydomain.com;
location / {
proxy_pass http://xx.xx.xx.xx:4080;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffering off;
}
}
And restarted my nginx service. In this config file I have two other server configs listening on port 80 that works fine.
My nodejs app looks like the following:
var express = require('express'),
http = require('http'),
https = require('https'),
fs = require('fs'),
Security = require('./security.js'),
json = require('express-json'),
stylus = require('stylus'),
nib = require('nib'),
path = require('path'),
bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());
app.use(json());
app.use(authChecker);
app.use(stylus.middleware({
src: __dirname + '/public',
compile: compile,
keepExtensions: true,
uploadDir: __dirname + '/public/images'}));
app.use(express.static(path.join(__dirname, 'public')));
require('./routes-v1.js')(app);
require('./routes-v2.js')(app);
var hskey = fs.readFileSync('certificates/key.pem');
var hscert = fs.readFileSync('certificates/key-cert.pem');
var options = {
key: hskey,
cert: hscert
};
http.createServer(app).listen(4080);
console.log('Listening on port 4080...');
https.createServer(options, app).listen(4443);
console.log('Listening on port 4443...');
function authChecker(req, res, next) {
console.log("authChecker");
res.setHeader('Content-Type', 'application/json');
if (!Security.checkHMAC(req)) {
res.json({unauthorized:true});
} else {
next();
}
}
function compile(str, path) {
return stylus(str).set('filename', path).use(nib());
}
My problem is that the newly defined urls in NGINX doesn't work. The IP's work fine. What am I missing here? Is it something in NGINX or in node? My other subdomains through NGINX works flawlessly.
