The error, as shown above, is Error R10 (Boot timeout )
-> Web process failed to bind to $PORT within 60 seconds of launch. I can think of two things that can cause this:
Your startup is taking a long time - for example you're calling out to external web services while starting.
Or you're not listening to the right port, so as a result you'll never bind to the right port.
I'm guessing it's the second? What PORT number do you use? Do you do something like this?
var port = Number(process.env.PORT || 5000);

I have deployed my webpage on Heroku, with MongoAtlas for hosting database. The site has been deployed successfully, but on opening the URL it shows the following error.
An error occurred in the application and your page could not be

You can do this from the Heroku CLI with the command heroku logs

What is the problem and how to solve it
I'm running a React.js/Node.js application on heroku. I have been successfully deploying for a while but after changing the code base yesterday The build is successful and I get an application error. Specigically what I changed in the code base was switching back from SASS to CSS na dadding OAuth to my nodemailer functionality.
I have checked all the environment variables and my port is set to process.env.PORT || 8080

I get an h10 error, and there is no other information. This application is running on the heroku free tier. Any suggestions as to why this is happeneing? I would be glad to upoad more code but I'm not sure what I would, especially since everything works locally.
It was the node version, Node released version 14 yesterday or something.
This question already has answers here:
Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

Closed 2 years ago.
My node app worked fine when I hosted it in Glitch and DigitalOcean server.
But it doesn't work when I try in Heroku.
Here's the log I get after running heroku logs --tail:

And here's the link to my repo: https://github.com/cuinjune/battle-square
What's the problem and how to fix this?
The cause is in the logs: Server is running localhost on port: 3000.
The app is using port 3000, locally is fine but Heroku gives you a dynamic port upon deployment, therefore you need to bind to this port which is provided through the env variable $PORT
I am trying to deploy my app (Node.js) on Heroku which uses a sqlite3 database, deployment is done but while running the app I am getting the following error:
2020-04-23T10:07:50.747074+00:00 app[web.1]: App started on port 5000

I appreciate your help.
It looks like your Node application is not starting properly. This is likely due to you not binding your Node server to the correct port.
On Heroku, you must bind your Node server to a port number specified in the PORT environment variable. This is because Heroku magically handles routing for your requests, on a server with many other applications.
What you should do is modify your Node code so that it listens on port process.env.PORT.
Here's an example Express.js application that listens to the correct port, as an example:
var express = require('express');
var app = express();
app.listen(process.env.PORT);
