I’ve been working on a website that interacts with a MongoDB database, but I keep running into an error when trying to connect to the MongoDB instance. The error message reads: “MongoError: connect ECONNREFUSED 127.0.0.1:27017”. This happens whenever I try to run my Node.js application.
Here’s my code:
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/myDatabase', {useNewUrlParser: true});
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
console.log("Connected successfully.");
});
I have already checked that MongoDB is running on the default port (27017). I have also tried using the IP address 0.0.0.0 instead of localhost, but that didn’t work either. What could be causing this error and how can I fix it? Any help would be greatly appreciated.

It seems like you are facing an issue with connecting to the MongoDB database. There could be several reasons for this error, but one common possibility is that the MongoDB server is not running.
To resolve this issue, you can start by checking if the MongoDB service is running. You can do this by running the following command in your terminal or command prompt:
“`sudo service mongod status“`
If the service is not running, you can start it by running the following command:
“`sudo service mongod start“`
If the service is already running, you can try restarting it and then attempting to connect to the MongoDB database again.
Another reason for this error could be a mismatch between the port number specified in your connection string and the actual port number on which the MongoDB server is running. Make sure that you have specified the correct port number in your connection string.
I hope this helps you resolve the issue. Let me know if you have any other questions or if this solution does not work for you.
