I am trying to set up MongoDB with Node.js and I keep getting the following error:

Uncaught MongooseServerSelectionError MongooseServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017

Here is my code:

const mongoose = require('mongoose')
mongoose.connect('mongodb://localhost:27017/mongotest')

Here is my database connection: mongodb connection

This is my first time attempting to use MongoDB and I am very new to node.js and programming as a whole, so the solution is probably very obvious.

atlas mongoose mongodb node.js

Your code is trying to connect to a MongoDB server running on localhost (which is your local machine), but your screenshot is showing an entirely different hostname.

So make sure you're actually using the correct hostname:

mongoose.connect('mongodb://mydb.kngo05j.mongodb.net/mongotest')

You may also need to pass login credentials. How to do that is explained in the Mongoose documentation.
