Making a droplet's nodejs accessible - along with apache

Hi,

I have just installed nodejs, and I have a script running that is listening on port 1337

ie.

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337);
console.log('Server running at 1337/');

I have run:

iptables -F 
iptables -A INPUT -p tcp -m tcp --dport 1337 -j ACCEPT

I did - and stiil do have apache running. And there is an SSL certificate operating on the Ubuntu server.

https://xxx:1337 (where xxx is known by the SSL cert) says ‘This webpage is not available’.

Of course, https://xxx brings up the page via apache.

Can I access nodejs while apache is running? What am I missing here?
