Warning-Duplicati.Library.Main.Operation.FilelistProcessor-MissingRemoteHash

Hi,
I try to backup a UnRaid server share by Duplicati run in a Docker container.
Backup in a cloud via WebDav is ok.
Backup in another UnRaid share is ok.
Backup to a local Netgear ReadyNAS has warnings a sometimes errors (see below).
Backup via Duplicati on Windows PC to the Netgear ReadyNAS is also ok.

What is the problem?
