Deploy Error: Health Checks When deploying simple node js + express app

Hello, i am trying to deploy simple node js + express app.


const express = require('express');
const app = express();
const port = 3000; // Change this to the desired port number

// Set up a route for version information
app.get('/version', (req, res) => {
  const nodeVersion = process.version; // Node.js version
  const expressVersion = require('express/package.json').version; // Express version
  const versionInfo = {
    node: nodeVersion,
    express: expressVersion

// Start the server
app.listen(port, () => {
  console.log(`Server listening on port ${port}`);

  "version": "1.0.0",
  "description": "Your application description",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",

    Hi there,

    It looks like that your app is listening on port 3000. This should also be the health check port, can you confirm if this is the case?

    What you could do is:

    • Go your DigitalOcean Control Panel
    • Click on Apps on the left menu
    • Click on your app
    • Then go to settings
    • Click on the Node.js component that you’ve deployed
    • Then go to health checks and set the type to TCP and the port to 3000

    After that save the settings and give it another try.

    Let me know how it goes!
