This was made intentionally. When the server is completely off i saw no real benefit in tracking its status and so having the widget being active all the time. But in fact i can't estimate if this would have a noticeable effect on cpu or battery.

At the moment when you start the server from command line for some reason you can make the widget start tracking just by pressing its button. The widget will recognize and display the server's real status and in addition give a respective note.

I think about adding a configuration window with an autostart option and an optional confirmation dialog when closing active connections. So maybe an option to keep tracking when the server is off might also be added.
