I just completed a sync backup to a Hetzner Storage Box via WebDAV. The sync itself worked flawlessly and quickly even though it was a fair amount of data. Weirdly, at the end of the sync / backup I get this error message now. I can still access my data via your app on the storage box via WebDAV so all good there. It feels like some kind of hand shake doesn’t work when there’s no further data to be backed up?
