回答1:

First of all: Are you certain that those are all of the necessary requirements?

If they are, are you sure you have any dynos allocated? What's the result of heroku ps? H14 is listed as usually being caused by having no dynos set to run your app.

You can set it to use one web dyno with heroku ps:scale web=1.
