Yamon no webui?

I have installed yamon inside a usb drive attached to my router and set the www path to inside installation directory that has an www folder.
and set the path to yamon (default) but opening doesn't says "Not Found The requested URL /yamon/ was not found on this server."

is it because I have moved luci port from 80 to 444 and used https?

also yamon logs are really messing uo my logread with log messages.
how do I disable that? ( is that the live messages)
and why stooping yamon4 service doesnt stop these messages?

There's a bug in the 4.0.6 and earlier installers. Read the post below for a solution.
