Hello @benoit
Your image that states No backup site for update looks like the configuration of the backup site might not be correct.
Please check the backup site content configuration if everything is included and Store automatic-update backups is selected.
Go to https://my.$DOMAIN.$TLD/#/backup-sites press the ... button and press Content.
It should look like this:

Please also share the logs of the backup that is failing.
A warning for Hetzner Storage Boxes.
Storage Boxes have a concurrent connections limit of 10.
If you use the same Storage Box for multiple Cloudron servers or other services the concurrent connection limit can be exausted leading to failures.
One example.
If you mount the Storage Box on 2x Cloudron servers and use the same Storage Box for 2x Volumes, 4x concurrent connections are persistently used.
Thus, only 6x connections are avaiable.
Just to keep that in mind when using Storage Boxes for multiple servers/services.
