Satelite Authentication Service stuck on Starting

Hello Everybody,
i'm new to this forum, so i hope i choose the right category.

We have a problem with ZENworks 11.4.3 Satellite. All our Satellite are configured to do user authentication. But the service always tells us "Starting". We have that on different Windows Machines (2008R2, 2012, 7, 10)

In the logfile i have the following entry:
[TRACE] [06/23/2017 09:02:06.415] [1348] [ZenworksWindowsService] [41] [] [AuthSatelliteModule] [] [DEBUG_VERSION : will retry to configure Authentication Satellite Server after waiting for 5 seconds
Type: Novell.Zenworks.AuthSatellite.AuthServerConfigureException
Message: Authentication server config data is invalid. One or more downloadable files are missing data

Does anyone have an idea?

Thank you very much in advanced!
