Heroku “State changed from starting to down Stopping all processes with SIGTERM”

After booting up my Node.js Heroku app with this Procfile:

web: node www/main.js

I used to get:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

So I have changed my Procfile to a generic command to get around this, following from here, using:

start: node www/main.js

And I am still getting a shut down after 60 seconds. This is the error(s) now:

2015-01-20T13:04:01.452819+00:00 heroku[worker.1]: State changed from up to starting 2015-01-20T13:04:02.728905+00:00 heroku[worker.1]: State changed from starting to down 2015-01-20T13:04:03.434251+00:00 heroku[worker.1]: Starting process with command node www/main.js 2015-01-20T13:04:03.874370+00:00 heroku[worker.1]: Stopping all processes with SIGTERM 2015-01-20T13:04:05.188100+00:00 heroku[worker.1]: Process exited with status 143 2015-01-20T13:04:05.930916+00:00 app[worker.1]: [Tue Jan 20 2015 13:04:05 GMT+0000 (UTC)] INFO Connecting... 2015-01-20T13:04:06.837197+00:00 app[worker.1]: Welcome to Slack.

I am using https://github.com/slackhq/node-slack-client and have not adapted the code too much. I have tried all the usual things and now I'm asking for help.

The other weird thing is that the Slack bot connects and is running perfectly for those 60 seconds.


socket = io.listen(process.env.PORT);

Do this in your main.js file, and revert back to web: node www/main.js
