Heroku now defaulting to SSL and app breaks if pushed there

[TechRsch]

I just used the "Deploy to Heroku" button to try it out on Heroku. It deployed fine and client access to the URL provided the expected screen. However, nothing worked from there.

I noticed that the client URL was using HTTPS. From my other Heroku apps, I understand that Heroku is now enabling HTTPS as the default. The app doesn't seem ready for that.

I then attempted client access by changing the protocol to HTTP and everything worked fine.
