I am following the https://www.mongodb.com/languages/mern-stack-tutorial guide. Then installed atlas using https://www.mongodb.com/docs/atlas/cli/stable/install-atlas-cli/ using windows binary installation.

I've set up everything according to the tutorials.

Versions:

  1. Node v18.6.0
  2. Npm v9.6.5
  3. Atlascli v1.6.0

I can't really change anything with the IP due to living in a dorm if that may be an issue.

config.env code (MYLOGIN AND MYPASS are taken from mongoDB database access):

ATLAS_URI=mongodb+srv://MYLOGIN:MYPASS@sandbox.jadwj.mongodb.net/employees?retryWrites=true&w=majority
PORT=5000

conn.js code:

const { MongoClient } = require("mongodb");
const Db = process.env.ATLAS_URI;
const client = new MongoClient(Db, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

var _db;

module.exports = {
  connectToServer: function (callback) {
    client.connect(function (err, db) {
      // Verify we got a good "db" object
      if (db) {
        _db = db.db("employees");
        console.log("Successfully connected to MongoDB.");
      }
      return callback(err);
    });
  },

  getDb: function () {
    return _db;
  },
};

Error message:

PS D:\**\mern\server> npm start

}

Node.js v18.6.0

What I've tried already:

  1. Adding a new database user with admin privileges (Authentication method is SCRAM).
  2. Setting network access to 0.0.0.0.
  3. Tried pulling the github repo https://github.com/mongodb-developer/mern-stack-example it results with the same issue.
  4. I have tried connecting to the database using the "MongoDB for VS Code" extension on VSCODE and it worked fine though when I do npm start it fails.

  • Maybe add [authSource](https://www.mongodb.com/docs/manual/reference/connection-string/#mongodb-urioption-urioption.authSource) to (or remove `employees` from) the connection string? – user20042973 Apr 19 '23 at 23:48
  • Maybe this one https://stackoverflow.com/questions/63754742/authentication-failure-while-trying-to-save-to-mongodb/63755470#63755470 – Wernfried Domscheit Apr 20 '23 at 04:28
  • Both answers didn't help, tried running on a different network, changing node versions, reinstalling atlas, other computer still fails. I swear it must be something with the mongodb cloud, thanks for trying to help though – maxiukas Apr 20 '23 at 17:39
