How to fix 'Error: querySrv EREFUSED' when connecting to MongoDB Atlas?

I am new to MongoDB 4.0.6 and tried to implement it into my website using Node/Express.js, but when I try to connect to mongodb+srv://${process.env.MONGOUSER}:${process.env.MONGOPASS}@main-03xkr.mongodb.net/main I'm getting this error:

{ Error: querySrv EREFUSED _mongodb._tcp.main-03xkr.mongodb.net at QueryReqWrap.onresolve [as oncomplete] (dns.js:199:19) errno: 'EREFUSED', code: 'EREFUSED', syscall: 'querySrv', hostname: '_mongodb._tcp.main-03xkr.mongodb.net' }

I've tried connecting to mongodb://localhost:27017/main, but this does seem work.

Here is the relevant code:

require('dotenv').config();
const mongoose = require('mongoose');

// Database
const uri = `mongodb+srv://${process.env.MONGOUSER}:${process.env.MONGOPASS}@main-03xkr.mongodb.net/main`;
const localURI = 'mongodb://localhost:27017/main';

var Project = require('./models/project');

mongoose.connect(uri, { useNewUrlParser: true });
const db = mongoose.connection;

db.once('open', () => console.log('Successfully connected to MongoDB'));
db.on('error', (e) => console.log(e));

// Routes
app.get('/', (req, res) => {
  Project.find({}, (e, projects) => {
    if (e) console.log(e);

    res.render('home.ejs', {
      projects: projects
    });
  });
});

So does anyone know how to fix this error and maybe explain what is happening here?
