I was able to get authomatic working behind an SSL proxy by using [`werkzeug.contrib.fixers.ProxyFix`](http://flask.pocoo.org/docs/0.12/deploying/wsgi-standalone/#proxy-setups) and adding `X-Forwarded-Proto: "https"` to my reverse proxy (Apache). Does Heroku not pass the `X-Forwarded-Proto` header?
