Node.js socket hang up error when connecting to twitter api

I'm getting socket hang up error , when connecting to twitter streaming api with basic authentication using https. I think the error is occurring when doing the authentication.

var https = require("https");
var options = {
        host: 'stream.twitter.com',
        path: '/1.1/statuses/filter.json?track=bieber',
        method: 'GET',
        headers: {
                "Authorization": "Basic " + new Buffer('UserName' + ":" + 'Password').toString("base64")
        }
}; //end of options


var request = https.request(options, function(response){
            var body = '';
             console.log('STATUS: ' + response.statusCode);
             console.log('HEADERS: ' + JSON.stringify(response.headers));

            response.on("data", function(chunk){
                    var tweet = JSON.parse(chunk);
                    console.log("Tweet " + tweet.text);
            });  // end of data

            response.on("end", function(){
                console.log("Disconnected!!");
            }); // end of end

            response.on("error", function(){
                console.log("error occured");
            }); // end of error
}); // end of request

request.on("error",function(error){
        console.log("Error: " + error.message);
                }); // end of error

When i try to access this url it works fine.
