NodeJS HTTPS request to Intersango.com

There is something wrong with the request I'm making and I can't figure it out. It seems everything is in order according to the API spec.

Here is the code:

var request = require('https').request;

var opts = {
  host: 'intersango.com',
  method: 'GET',
  path: '/api/ticker.php',
  port: 443,
  accept: '*/*',
  headers: { 'User-Agent': 'Mozilla/5.0 (X11; Linux i686; rv:10.0) Gecko/20100101 Firefox/10.0' } };

var req = request(opts, function (result) {
        result.setEncoding('utf8');
        var buffer = '';
        result.on('data', function(data) {
            buffer += data;
        });
        result.on('end', function() {
            console.log('<- Received ' + buffer.length + ' bytes');
            var data = JSON.parse(buffer);
            console.log(data);
        });
    });

req.on('error', function(e) {
        console.log('warning: problem with request: ' + e.message);
    });

console.log('-> ' + opts['method'] + ' ' + opts['host'] + ':' + opts['port'] + opts['path']);

req.end();

Here is the output:

$> node test.intersango.js
-> GET intersango.com:443/api/ticker.php
warning: problem with request: socket hang up

Interestingly, if you go to https://intersango.com/api/ticker.php in your browser its fine, but not if you just go to intersango.com:443/api/ticker.php. I tried some other ports but it just gives warning: problem with request: connect ECONNREFUSED

Note: trying POST doesnt help either
