The issue you are facing:
I set up a new nextcloud instance with Wasabi S3 as primary storage and ldap users. Everything worked fine, and users were created. Unfortuantely now I do have a issue that (after tranferring a amount of GB of data from the old nexcloud via external stoage) I can’t access the files on the S3-Storage anymore.

A php8.1 occ files:scan
Starting scan for user 1 out of 1 ()
Path not found: /

Does anybody have some hints how can I restore/access the data again and how can I make the S3 object storage more relaible in future?
thanks
