Hey everyone,
I am using Duplicati to backup from two RaspberryPi to a Hetzner StorageBox via SFTP. Both are running the latest linuxserver docker image.
On one of them, the Backups are already running for several months, on the other I recently switched the backend to this StorageBox.
When I did this, I started getting this error on the new instance:

On the SFTP server I can see that some files were created but they all have a size of 0 bytes.
First, I wasn’t sure what I could do about this, then I tried connecting via SFTP inside the container’s shell which worked. Suprisingly afterwards a backup via Duplicati also worked. On the next scheduled run, I got the same error again. Now I added a script to run before my backup starts which just connects once to the SFTP server, does ls and exits which again allows the backup to go through.
I also figured out that if I need to upload a larger amount of data (e.g. for the initial backup) it would fail even after doing this initially. When looking at the live log, I noted that at some point the counter of uploaded bytes got stuck. If it didn’t change for half a minute or so, I again executed the sftp command on the shell and it started uploading again for some time.
On the other RaspberryPi I have no issue at all with identical backup configurations.
Anyone has an idea what could cause these issues?
