simple todo app, can't connect to mlab db - node

I am following this tutorial and for some reason I am being refused a connection from the mlab db that I have created.
MongoError: failed to connect to server [ds041516.mlab.com:41516] on first connect

server.js

var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');

var index = require('./routes/index');
var todos = require('./routes/todos');

var app = express();

// View Engine
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.engine('html', require('ejs').renderFile);

app.use(express.static(path.join(__dirname, 'client')));

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

app.use('/', index);
app.use('/api/v1/', todos);

app.listen(3000, function(){
    console.log('Server started on port 3000...');
});

routes/todos.js

var express = require('express');
var router = express.Router();
var mongojs = require('mongojs');
var db = mongojs('mongodb://aaron:aaron@ds129260.mlab.com:29260/todosmeanaarondev',['todos']);

// Get Todos
router.get('/todos', function(req, res, next){
    db.todos.find(function(err, todos){
        if(err){
           res.send(err); 
        } else {
           res.json(todos);
        }
    });
});

module.exports = router;

Unsure if there is another way of retrieving the db. Thanks
