Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

Question

I have my first node.js app (runs fine locally) - but I am unable to deploy it via heroku (first time w/ heroku as well). The code is below. SO doesn\'t let me write so much

Answer 1

I had the same issue because I didn't define Procfile. Commit a text file to your app's root directory that is named Procfile without a file extension. This file tells Heroku which command(s) to run to start your app.

web: node app.js

Answer 2

A fixed number can't be set for port, heroku assigns it dynamically using process.env.PORT. But you can add them both, like this process.env.PORT || 5000. Heroku will use the first one, and your localhost will use the second one.

You can even add your call back function. Look at the code below

app.listen(process.env.PORT || 5000, function() {
    console.log("Server started.......");
});

Answer 3

I had same issue while using yeoman's angular-fullstack generated project and removing the IP parameter worked for me.

I replaced this code

server.listen(config.port, config.ip, function () {
  console.log('Express server listening on %d, in %s mode', config.port, app.get('env'));
});

with

server.listen(config.port, function () {
  console.log('Express server listening on %d, in %s mode', config.port, app.get('env'));
});

Answer 4

In my case, I was using example from https://hapijs.com/

To fix the problem I replaced

server.connection({ 
    host: 'localhost', 
    port: 8000 
});

with

server.connection({
    port: process.env.PORT || 3000 
});

Answer 5

Changing my listening port from 3000 to (process.env.PORT || 5000) solved the problem.

Answer 6

I had same issue I could resolved issue with replace 'localhost' with IP which is '0.0.0.0'
