Big Troubleshouting No file openable


Our server stop without apparent reason. Then when it restart, the dev path of the disk have changed without warning. Has I did have the same folders on both drive I did not see at first look that the drive was not set correctly.
Whatever, Owncloud started with an empty folder and it remove files from user desktop while synchronising it (That is a quiet strange behavior).
Then we discovered that the folder was not the good one, we down owncloud container, change the disk mounted configuration, remount at the correct position, restart owncloud docker container and , run a files:scan --all to reupdate owncloud database.
The owncloud server is running with encryption module with user encryption level.

But any file we try to get, we got the message :

Ce site est inaccessible
Il se peut que la page Web à l’adresse >https://xxxxxxx/remote.php/webdav/XXXXXXXXXXXXX/XXXXX/BLOGS%20France/Blogueurs%20Francophones.xlsx soit temporairement inaccessible ou qu’elle ait été déplacée de façon permanente à une autre adresse Web.

And I can open any files.

Actual behaviour

Can’t open any files

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

Are you using external storage, if yes which one: local/smb/sftp/…

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/…

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.
