Is this link still valid? I tried using it today, but I'm getting an insecure connection from Firefox.
Thanks!

Its working, however main website uses HSTS now, that requires to include sub domains for higher score in SSL labs. Because of that, our custom domain cert now give you false error. We probably have to move it under different domain in order to make a work around. Thank you for bringing it to us.
