Es wurde weder der User "admin" noch sein PW auf der Syno geändert.
User "admin" ist auf der Syno in der Gruppe der Administratoren.
Ein Neustart der Syno brachte keinen Erfolg.
Das Passwort im Adapter falsch einzugeben um speichern zu können und dann wieder auf das richtige PW zu speichern, kein Erfolg.

Ausständig wäre noch eine Deinstallation des Adapters und das Löschen aller DP und danach eine Neuinstallation.
