Many Problem after Update 15.0.4


my Nextcloud run in a Docker container, for the database I use a Docker with MariaDB. Everting run well.
After the last updates there are many problems.

There is no problem with the sync between macOS desktop and the Nextcloud. No problem with the
contacts or calendar (macOS and iOS).

But the Nextcloud iOS app (2.23.0) have many problems. "Read Folder WebDAV: items NULL please fix or
internal server error. In the protocol are for example Uncaught Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occured in driver: SQLSTATE[08004] or new error Sabre\DAV\Exception\UnsupportedMediaType: This resource only supports valid vCard or jCard data. Parse error: Invalid Mimedir file. Line starting at 75 did not follow iCalendar/vCard conventions

I clean one IOS installation, after that no chance for login: CSRF check failed.

I don´t understand were the problem ist. Is the iOS app buggy or the Docker container.
