Hi Leo,
I have been having a similar problem and have now after a lot of blood sweat and tears logged it as a bug to the Moodle Tracker.
Try as I might, I can not get this feature to work.
I have a suspicion that what has happened is:
1) The feature Munster university built into OwnCloud which linked files "dynamically" to Moodle has not been included in this package.
2) The access controlled link feature is actually a feature that is more intended for when students submit work work rather than for developers to link file to Moodle for students to access.
Once I get an answer back from the developers, I can let you know where we stand.
In the meantime, try to ensure you have the latest version fo NextCloud installed.
