Two servers on the same network "confuses" Samsung-F?

If I am running two Serviio servers on the same network (two notebooks), the Samsung-F series shows only the last started one, but can not list the content and shows a connection error.
I can live with it, I am just curious whether it should work.
Does anybody have any suggestions or experiences?
