Most likely your mysql server is not running, or running on a different port/interface.

So i was working on a login system with MySql. At first it worked perfectly, but after a bit of time it stopped working and now when I start it it gives me

What is also important to say is that I do not host the Database on my PC, I have rented a server for it. Hope that someone can help
I tried a basic beginner program in Node.Js where I wanted to use the built-in module 'http'. After executing a basic program of http.createServer(). Below is my source code.
var http = require('http');
http.createServer(function (req, res) {
res.write('Hello World!');
res.end();
}).listen(8080);
When running the code in cmd it didn't run and displayed the following error.
events.js:287
throw er; // Unhandled 'error' event
^

Ok, it's not problem in your code actually 8080 already running anywhere else so you can't run the same port number at a time so just close all running process Or you just shut down your PC and run again the problem will be resolve.
I used to run mysql using xampp, do I have to run mysql service?
I followed this tutorial -> http://mfikri.com/en/blog/nodejs-mysql-crud

It seems like the connection to your db was refused. Make sure you are using the correct database account and that it has privileges.
Also make sure to whitelist your app from db.
You need to whitelist the following ips: 127.0.0.1 and localhost
this thread can possibly be of help: node.js mysql error: ECONNREFUSED
Yes, you need a MySQL DB running. The easiest way is to install Docker on your machine, and use the official MySQL container.
I am trying to deploy my node app to Heroku.
I have added the MLab MongoDB add on and have set the config variable
$ heroku config
=== thevoyageapp Config Vars
MONGODB_URI: mongodb://heroku_f80ngvbz:btt04p7erog80#ds.mlab.com:11/herokgvbz
And have added the process.env.MONGODB_URI to my mongo connection
const mongoose = require('mongoose');
let url = process.env.MONGODB_URI || 'mongodb://localhost/trip';
mongoose.connect(url, { useMongoClient: true });
But I still get this error:

Any idea what could be the issue?
It is highly possible that you forget to whitelist the server IP to access MongoDB database. You can whitelist the IP at MongoDB Atlas.
I want host my ExpressJS (AdonisJS) application on PM2.

Have you tried sudo pm2 appname? You need sudo access for port 80
