Problems Loging in on Mobile Devices?

Hello, there wonderful people. The question is, has anyone had a problem logging on to this forum from a mobile device, like iPhone or iPad? I joined recently and can log on via PC with no problem, but when I log on with my iPhone or my iPad, I get an error. It will not allow me to log in or prompt for 2FA. It looks like Safari is not picking up the SSL Certificate. Is anyone else experiencing this?

I figured it out, I was trying my.Horner.de, and I needed to enter the https:// in front of it. On PC it did that by default. All is well now.
