Troubleshooting
Where to look when it won't start, open, import, or share.
First, check that Caramel Board Desktop is running and that the storage drive has free space. If that doesn’t fix it, check the following by symptom.
The app won’t start
- The first launch shows an OS confirmation → Install steps
- If your data store is on an external drive, connect it before launching
The browser won’t open it
- Reopen it from “Open Browser” in the Desktop app
- Check that the URL is
http://127.0.0.1:6777
Can’t add videos, GIFs, or PDFs
FFmpeg (video and GIF) or Poppler (PDF) may not be set up. Check the detection status in settings. → Set up external tools
Thumbnails or previews don’t appear
- For a single item, use “Refresh” in the context menu
- For a wide range, use “Full Refresh” (incremental) in Settings > Libraries → Manage libraries
Can’t view from a phone or tablet
- Check that sharing is on → View from a phone or tablet
- Check that the PC and device are on the same network and the URL is correct
- Check that the OS firewall isn’t blocking it
AutoTag isn’t working
- Check that the model is installed → AutoTag
- Check that the “JoyTag Server” on the AutoTag screen is running
Something’s off after an update
An automatic backup is created before a database update. You can recover from the backup at the path that was shown. → Data store and backup
