MongoDB via Mlab - MongoError: Authentication failed

Question

I am creating a simple server using nodejs, expressJs and mongodb

here is server.js

const express        = require('express');
const MongoClient    = require('mongodb').MongoClient;
const bodyParser     = require('body-parser');
const db             = require('./config/db');
const app            = express();
const port = 8000;
app.use(bodyParser.urlencoded({ extended: true }));
MongoClient.connect(db.url, (err, database) => {
  if (err) return console.log(err)
  require('./app/routes')(app, database);
  app.listen(port, () => {
    console.log('We are live on ' + port);
  });               
})

Note: database info are all okay,

when i run node server.js , i get the following error :

    C:\Users\Bonge\Documents\Projects\movies_database>node server.js
{ MongoError: Authentication failed.

  name: 'MongoError',

what is wrong with my code?

show your db config file and have you checked https://stackoverflow.com/questions/30924859/unable-to-connect-to-mongolab-getting-mongoerror-auth-failed — Gaurav Paliwal, Jun 18 '18 at 18:19
What is your mongoose and mongodb version? And also the config file — Ashh, Jun 18 '18 at 18:26
@GauravPaliwal `module.exports = { url: "mongodb://dbnameusername:dbpass@ds255260.mlab.com:55260/dbname" }` — Hot Zellah, Jun 18 '18 at 18:41
@HotZellah Is `dbname` the authentication DB name? Because if not, you shouldn't be passing it.. — Vasan, Jun 18 '18 at 18:45
make sure your `username`, `password` and `dbname` doesn't contain special characters like `@,-,+,`,+` — Ashh, Jun 18 '18 at 18:51
@HotZellah The [doc](https://docs.mongodb.com/manual/reference/connection-string/) says this: _Optional. The name of the database to authenticate if the connection string includes authentication credentials in the form of username:password@. If /database is not specified and the connection string includes credentials, the driver will authenticate to the admin database._ — Vasan, Jun 18 '18 at 18:51
