Two facts:
1) In server panel - Connected clients, when you show the connection duration time is there any way to show it in human-readable format (actually it shows something that seems <unix timestamp> or <centisecond>) ?
2) When trying to kick-off a connection, from within server-manager after confirmation I get:
An error occured while connecting to the manager. Check the service is running.
Looking at the log:
