Here nextcloud works in docker. Since a few days I get in my nextcloud synchronization client on the PC the message: Server is temporarily unavailable and I can not perform synchronization. I can see that the file system running Nextcloud uses acl with 'execute' for others. I fix it on 'no rights' for others and after a reboot of omv the rights for 'others' are set to 'execute' again. How can I firmly anchor this?
