Missing Thumbnails, Loading Hang, and Failed Fetch Errors
I’m running Immich on a Raspberry Pi 4 (8GB) and I’m running into a couple of recurring issues that I can’t seem to resolve.
Setup: - Raspberry Pi 4 (8GB) - Images stored on Synology NAS, mounted via SMB (files are accessible), login only has reading access - No reverse proxy or external access — only used locally - Same issues occur across different devices and even in incognito mode
Problems: 1. Thumbnails not generating - I often get
xx failed
xx failed
messages when generating thumbnails. - Downloading photos works fine, so Immich does have access to the files. - Manually refreshing thumbnails for a specific photo doesn’t work either. - Using “Load missing thumbnails” also results in the same
xx failed
xx failed
errors.
2. Immich sometimes stuck on logo - Occasionally Immich hangs on the loading screen (rotating logo forever). - The only way to fix it is restarting the container.
3. Frequent fetch errors - Example error:
Failed to fetch dynamically imported module: http://PRIVATEIP:2283/_app/immutable/nodes/19.X-TmAtSW.js (500)
