https://devcenter.heroku.com/articles/error-codes You are getting the error H10 App crashed. The problem could be anything.

Sadly the error log isn't helpful here. It looks like you did define a Procfile and you did bind to the $PORT (else you'd be seeing a different error message).

There has been a similar question about it here: Heroku deployment error H10 (App crashed)

I ran into the same error above, app was crashing on heroku (running fine in dev) but error logs on heroku were not revealing any clues. I read other answers on this page and broke out in a sweat after seeing "rebuilding the app." I figured maybe I could get in the heroku console and look around. I did and even the console crashed, but this time it told me why. It was some obscure variable I forgot to delete during a troubleshooting session hours earlier. I am not saying you will run into the same problem, but I found more info when I tried to go through the console. Hope this helps.

$ heroku run rails console

With this you can get a better error log pointing you towards the problem.
