Node JS :: Log in to Dashboard using username password fails

When i tried to log into one website using username and password through node.js; It always redirect to home page without redirecting to dashboard.

But when i tried same login via browser it shows following header.

This is the code i've used.

var request = require('request'),
cheerio = require('cheerio'),
querystring = require('querystring'),
cookieParser = require('cookie-parser'),
url = "https://www.revcontent.com/login";

// creating a clean jar
var j = request.jar();

var request = request.defaults({
    jar: j,
    followAllRedirects: true
});

var stringify = require('node-stringify');

//Login Credentials
var username = "xxxxxx";
var password = "xxxxxxx";
var url = "https://www.revcontent.com/login";
var url2 = "https://www.revcontent.com/widgets?filter_search=&tab=countries&devices=&country=&domain=test.com&start_date=2017-01-22&end_date=2017-04-22";

var cookie = request.cookie('revcontent.com');
j.setCookie(cookie, url);


request({url: url, jar: j}, function (error, response, body) {

    if (!error) {
        var $ = cheerio.load(body),

        //Retriving CSRF Token
        csrf = $("[name='rv_tsvm']").val();
        console.log("Token = " + csrf); 

        console.log(j);

        var form = {
            login: 'Sign+In',
            name: username,
            password: password,
            rv_tsvm: csrf,
        };

        var formData = querystring.stringify(form);
        var contentLength = formData.length;

        request({
            headers: {
                'Content-Length': contentLength,
                'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
                'Content-Type' : 'application/x-www-form-urlencoded' 
            },
            uri: url,
            body: formData,
            method: 'POST',
            jar: j
        }, function (err, res, body) {

        console.log(res);

        if(err) {
            return console.error(err);
        };
        });

    } else {
        console.log("We’ve encountered an error: " + error);
    }
});
