As you can see, https in in use here and there is no problem logging in. So this is not a bug, but an error in the installation / configuration. Have you double checked app.yml for errors? ---

If it is specific to a browser, sounds like an issue with your SSL cert. Where did you purchase your SSL cert from? ---
