I tried loading over HTTPS and got the following error:

    This server could not prove that it is
    worldcup.sfg.io; its security certificate
    is from *.herokuapp.com. This may be
    caused by a misconfiguration or an
    attacker intercepting your connection.

I'll look into HTTPS, heroku says it is configured fine for worldcup.sfg.io, browser says it isn't, browser wins :)

I have the same issue. Can't use inside my Preact component running on a https site.
