$ foreman start\n<\/code><\/pre>\n
creates a link with my working app I have a file Called Procfile that contains:<\/p>\n

Here is my package.json<\/p>\n

a little later<\/p>\n
$ heroku ps\n=== web (1X): `node server.js`\nweb.1: crashed 2013\/09\/27 22:11:49 (~ 10s ago)\n<\/code><\/pre>\n

  1. \n
    I can’t be sure without the Node code where you create the server, however from the logs it looks like you are not listening on the correct port.<\/p>\n
    Heroku assigns your application a port (which is set as the “PORT” environment variable) that your application must listen on. If you do not connect to this port within 60s, it will kill your app, and this seems to be what is happening.<\/p>\n
    UPDATE: In fact, based on your web.1 log entry, it looks like you are trying to listen on port 8080. I think it is highly unlikely that this is the port provided by Heroku. You can get the port Heroku provides from process.env.PORT, and then listen on that.<\/p>\n<\/li>\n
  2. \n
    try looking in your dashboard check that you have at least one Dynos. It’s happen to me that I add more than one app and I use the free trail so it keep moving the Dyno between the app.<\/p>\n
    Good Luck.<\/p>\n<\/li>\n<\/ol>\n
