Deployment on App Platform Successful but Local Host Error

Hey Mireya! 👋

I believe that the App Platform automatically sets the PORT environment variable so you need to make sure your app is using this variable instead of hardcoding localhost or a specific port.

In your package.json or server setup, it should look like this:

const port = process.env.PORT || 3000;
app.listen(port, () => {
  console.log(`Server running on port ${port}`);
});

Also can you share your Run Command that you’ve defined in the App Platform settings?

Besides that, your app should bind to 0.0.0.0 instead of localhost to accept external traffic, this usually looks as follows:

app.listen(port, '0.0.0.0', () => {
  console.log(`Server running on port ${port}`);
});

Let me know how it goes!
