X4S R7800 wont forward 443 ssl port

Hello, I am trying to forward port 443 to a webserver but it wont forward it. I've read others having the same problem beacuse of remote managment so Ive disabled it. I've also read about USB support beeing the problem so I've disabled it as well. A third tip was UPnP so i've disabled that as well still no go. Is this a problem with the router or is it actually solvable?

Im using firmware version 1.0..2.7.4 wich is currently the latest one.
