Error : “Could not connect to any servers in your MongoDB Atlas cluster”

问题

My node app gives me this message "Could not connect to any servers in your MongoDB Atlas cluster. Make sure your current IP address is on your Atlas cluster's IP whitelist".

I've already added my current IP address along with the 0.0.0.0 on the IP whitelist.

Below is a picture of the error message and the code I've written to connect it. I'm new to node.js and mongodb. I looked through all the solutions on here but none of them were able to solve this.

var express = require('express');
var bodyparser = require('body-parser');
var mongoose = require('mongoose');

var app = express();
app.use(bodyparser.json());

mongoose
     .connect("mongodb+srv://<username:password>@my-cluster.mongodb.net/test?retryWrites=true&w=majority", 
     { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true })
     .then(() => console.log( 'Database Connected' ))
     .catch(err => console.log( err ));

    app.listen(3003)

This is the error I receive after running nodemon.

Error Message and code

回答1:

Are you using proxy?? please try with different internet connection first.

回答2:

Try doing this:- MongoDB Atlas -> NetworkAccess -> Edit -> Allow Any

This worked for me!

回答3:

It's not always problem with the ip. Can have problem in db name , username or password.Then also connection failed.

回答4:

At times, it may be due to system settings as well.

In my case it was server system's date & time, it was not updated to current date & time settings, hence the connection to db from the server was refused. Updated the same, and restart the server, connection was successful.

回答5:

Try keeping these questions in mind when you face such an issue with your mongodB that:

Did I changed my IP address before I started working with my mongodb again after a long break? If no, then please change it because usually mongodb removes it after every 6 hours.

Did I moved from the place where I worked last time? If yes, then please change your IP again and activate it.

Please do visit the link https://studio3t.com/knowledge-base/articles/mongodb-atlas-login-ip-whitelisting/#whitelist-multiple-or-additional-ip-addresses and learn more about why you get such error and how deal with them. It helps a lot.

回答6:

To whitelist an IP address, go to your target cluster on MongoDB Atlas. Next, go to Network Access under the Security tab. On the IP Whitelist tab, click on Add IP address. Type your IP address manually under Whitelist Entry, then click Confirm. run your code it should run without any problem.

回答7:

Not sure if it is the right reason. But, its working for me when i disconnect the VPN.

When connected to VPN, I'm getting below error message.
