Attempting to get completely free SSL on Heroku using Cloudflares new free Universal SSL

Read this article: http://mikecoutermarsh.com/adding-ssl-to-heroku-with-cloudflare/

Which seems to suggest its possible now that Cloudflare offers SSL for free.

The steps I took:

Set up my DNS with Cloudflare (free account)

Forwarded my domain to my herokuapp (CNAME example-app.com -> example-app.herokuapp.com)

Set the Cloudflare SSL option to 'Full SSL'

Added my domain to my heroku app

Forcing https with this express middleware: app.use(function(req, res, next) { if (req.headers['x-forwarded-proto'] != 'https') { res.redirect('https://' + req.headers.host + req.path); } else { return next(); } });

The heroku domain http://example-app.herokuapp.com works correctly and redirects to https://example-app.herokuapp.com, green lock and all.

Both http://example-app.com and https://example-app.com do not work. The browser tab icon just keeps spinning and never resolves. Any ideas on how to get this working? Is this even possible?

*UPDATE

This is looking like it IS actually possible. From CloudFlare support:

Hi Bill, Fundamentally, as long as the "origin" supports an SSL connection you can use Full SSL with CloudFlare. Simon

CloudFlare released this blog post today: https://blog.cloudflare.com/universal-ssl-be-just-a-bit-more-patient/

My site has started resolving, but getting a "Your connection is not private" message like in the "Errors you may see" part of the blog post. Also in my CloudFlare settings there is a "SSL issuing" alert, so I imagine once it is issued this may just work. I'll keep y'all posted.
