I have installed Web Yast followed this tutorial: openSUSE:WebYaST Installation - openSUSE

I checked if the webyast service is running and it is running. I started webyast applet in my KDE and i clicked on it and tried to enable webyast. The icon is unfortunately still grey and I can't connect to webyast at all.

No error, no message, nothing.

Is there any log or something I can check? Do I need to install web server to make it work?
