Couldn't connect to mongodb on mongodb-atlas

问题

Trying to connect to the mongodb free database on mongodb-atlas I've almost tried everything Checked the docs, Changed the url, Changing password and even deleted the user and created the new one but still not resolve the problem

here is myurl.js file

module.exports = {
    mongoURL: "mongodb+srv://nansDB:nansDB123@nodecluster-qs6cv.mongodb.net/test?retryWrites=true&w=majority",
    secret: "mystrongsecret"
}

here is my index.js file

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

//mongodb Configuration
const db = require('./setup/myurl').mongoURL;

//attempt to connect to database
mongoose.connect(db,  { useNewUrlParser: true })
        .then(()=> console.log('MongoDb Connect successfully'))
        .catch(err => console.log(err));

const port = process.env.PORT || 3000;

here are the error lines I'm getting whenever I tried to run

{ MongoNetworkError: failed to connect to server [nodecluster-shard-00-02-qs6cv.mongodb.net:27017] on first connect [MongoNetworkError: connection 5 to nodecluster-shard-00-02-qs6cv.mongodb.net:27017 closed]

回答1:

Its solved actually my whitelisted ip was changed because of connection issue [reconnecting to wifi]. Although my suggestion is checked whether the ip you whitelisted is exists or not.
