Issue connecting to servers within the designated MongoDB Atlas Cluster has caused a mongoDB error

const mongoose = require('mongoose');

mongoose.connect('mongodb://DATABASE_LOGIN1:[MyPass]@mee6copycluster-shard-00-00.r86qy.mongodb.net:27017/djsdashboard/?authSource=admin', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

Error : 

UnhandledPromiseRejectionWarning: MongooseServerSelectionError: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted. Make sure your current IP address is on your Atlas cluster's IP whitelist

I am facing this issue and need assistance in resolving it. If you require additional information, please specify!

The error message obtained when using mongodb+srv://DATABASE_LOGIN1:[MyPass]@mee6copycluster-shard-00-00.r86qy.mongodb.net/admin?retryWrites=true&w=majority is as follows:

Answer №1

Dealing with a similar problem, I managed to solve it by clicking on the "Allow access from anywhere" option within the "Network Access" section of my MongoDB dashboard.

This issue may arise from connections through VPNs or proxies.

After doing this, you should now be able to connect to the server and port you designated.
