node.js - MongooseError [MongooseServerSelectionError]: connection <monitor> to 52.6.250.237:27017 closed

Question

I am trying to save data in mongodb through post method and using mongodb atlas with node.js but it keeps giving me an error, I provided correct connection string and correct password. Please help in regarding this issue. Thanks.

Here is the code:

const mongoose = require('mongoose');

const monngodb_url="mongodb+srv://maarij:[email protected]/authDB?retryWrites=true&w=majority";

mongoose.connect(monngodb_url, {useNewUrlParser: true,useUnifiedTopology: true}).then(()=>{
    console.log("mongodb is connected");
}).catch((error)=>{
    console.log("mondb not connected");
    console.log(error);
});

Here is the error:

server is running on port 3000
{ name: 'myName', email: '[email protected]', password: 'abcdefg' }
mondb not connected
