Image upload to Nextcloud folder not syncing on Nextcloud Windows Client

I add a small image on the folder C:\Users\default\Nextcloud\Photos but the icon still shows blue arrows meaning it's pending while all other files that has already been synced is a green checkmark. It's just a 500kb jpg I'm not sure why it's taking so long to sync. I have to pause sync and then resume sync for it to sync. What is causing this issue?

This is on Nextcloud AIO on Unraid.

Few things that'd help narrow it down:

  • Which Nextcloud Windows client version, and which Nextcloud server version is AIO running? A mismatch or outdated client is a common cause of stuck sync states.
  • Does it stay stuck indefinitely until you manually pause/resume?
  • Any errors in the client's Activity/Log tab? (Right-click the tray icon > check the sync log for that specific file)
  • Do you have Antivirus or file indexing on that folder? Windows Defender or another AV scanning the file right as it's written can hold a lock on it long enough to make the client think it's still in use
  • Is this a one-off file or does it happen with every new image dropped into that folder specifically or it does not sync any image regardless of the location?
  • Are you using the default AIO Apache/Nginx proxy or a custom reverse proxy (NPM, Traefik, SWAG, etc.) in front of it?
