Getting an error: "querySrv ECONNREFUSED _mongodb._tcp.cluster0.vxgqt.mongodb.net" when connecting to mongodb atlas

Question

I am getting the below error in the terminal: Error: querySrv ECONNREFUSED _mongodb._tcp.cluster0.vxgqt.mongodb.net did not connect on running the index.js file It was working fine till yesterday and today on running it is giving this error. This is the code snippet:

import express from 'express';
import bodyParser from 'body-parser';
import mongoose from 'mongoose';
import cors from 'cors';

import postRoutes from './routes/posts.js';

const app = express();

app.use(bodyParser.json({ limit: '30mb', extended: true }))
app.use(bodyParser.urlencoded({ limit: '30mb', extended: true }))
app.use(cors());

app.use('/posts', postRoutes);

const CONNECTION_URL = 'mongodb+srv://<username>:<password>@cluster0.vxgqt.mongodb.net/myFirstDatabase?retryWrites=true&w=majority';
const PORT = process.env.PORT|| 5000;

mongoose.connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => app.listen(PORT, () => console.log(`Server Running on Port: http://localhost:${PORT}`)))
  .catch((error) => console.log(`${error} did not connect`));

mongoose.set('useFindAndModify', false);

NOTE: I have provided the correct username and password in the connection url

I found a temporary fix and that is working: Under connect your application in MongoDB Atlas I selected node version 2.2.12 or later instead of 3.6 or later(which I used earlier). By selecting this, the application is now working fine as before
