The supposed installation process in CWP does not start by itself anymore.

The only option left is to manually install it from  SSH using the kickstart.sh, requiring a lot of afterworks, especially for password protecttion

I think the idea was to provide a seamlessly integrated netdata with password protecton out of the box.....accessible from the controlpanel as well as from outside.

Have you tried this?
