First and foremost consider this:

✔️ Only RetroArch bugs should be filed here. Not core bugs or game bugs
✔️ This is not a forum or a help section, this is strictly developer oriented

Description

Apple TV, latest tvOs, latest RetroArch from AppStore 1.19.1 (Git e2f91d8b5f) Apple TV has perfect stable network wired connection.

CloudSync is enabled, first sync completed successfully. Syncing only between one client and server, just for backup.

The second and all subsequent synchronisations fail. I see green notification "CloudSync finished with failures".

Log:

Files manifest.server (both Apple TV/RetroArch/downloads and on webdav server) and manifest.local is absolutely identical with valid json.

Expected behavior

Notification should not be green
I'm sure something was broken in sync process or something broke the file on the server. I didn't touch the files on the server. Only the RetroArch has access there.

Actual behavior

See description. Obscure error in the log and green error message in the UI 🤷🏻‍♂️

Steps to reproduce the bug

configure CloudSync, turn on, reboot the app
first sync should complete successfully
trigger sync anyhow - reboot the app or load-n-close any content
error should be here, in my case
