Veyon Master shows many copy's of teacher screen

[Skysoft]

Something strange is happening. Veyon is working fine in my classroom. But when a student shuts down his computer, the thumbnail in Master shows my (teacher) screen. When all computers are shutdown, i end up with many of "my" screens in thumbnail.

anybody any idea what i'm doing wrong ?

That's indeed a strange behavior. Are you using the builtin network object directory, i.e. added the student computers manually in Veyon Configurator? If so, did you enter IP addresses or host names in the host address column?
