Successfully connect MongoDB at home but in vain in office

I am new to coding. I know it’s probably a dumb question to everyone, but it’s still quite confusing to me.

I tried in vain to connect MongoDB in office but it completely works at home.

Here my code:

const express = require('express');
const mongoose = require('mongoose');

const app = express();

const dburl = 'mongodb+srv://admin:[email protected]/testing?retryWrites=true&w=majority'

mongoose.connect(dburl, {
    useNewUrlParser: true,
    useUnifiedTopology: true
})
    .then((result) => {
        console.log(result);
    })
    .catch((err) => {
        console.log(err);
    });



app.listen(3000, () => {
    console.log('listening to port 3000');
});

And I got this error message:

Node.js v20.2.0
[nodemon] app crashed - waiting for file changes before starting...
[nodemon] restarting due to changes...
[nodemon] starting `node app.js`
listening to port 3000
Error: querySrv ENOTFOUND _mongodb._tcp.cluster0.954cidx.mongodb.net
    at QueryReqWrap.onresolve [as oncomplete] (node:internal/dns/promises:251:17) {
  errno: undefined,
  code: 'ENOTFOUND',
  syscall: 'querySrv',
  hostname: '_mongodb._tcp.cluster0.954cidx.mongodb.net'
}

Honestly, I can’t even understand a single word in it. Could anyone help me to figure out what’s happen?
