When I tried to git push to Heroku, the following error occurred.

$ git push heroku master

 !  Heroku Git error, try again shortly.
 !  We've been notified, see http://support.heroku.com if the problem persists.

fatal: The remote end hung up unexpectedly

Since there might be an issue on Heroku’s side, I accessed http://support.heroku.com and https://status.heroku.com/ to check if any outages were occurring.

In my case, after waiting a few minutes and trying git push again, it pushed normally.

That’s all from the Gemba about resolving “Heroku Git error, try again shortly.”
