Thanks, that user even registered to my website and locked himself out due to too many login attempts. 😛

I’m using W3 Total Cache, CloudFlare and my webhost is using varnish.
I made sure that I’ve cleared all of these caches.

It looks like it just magically started working again, not sure for how long.
Can you as an outside visitor confirm this? (it should redirect to HTTPS)
