## Troubleshooting

- **403 / 401 on download** - the source URL requires authentication.
  Download Link cannot forward cookies or custom headers; use a tool
  that can authenticate with that service, or paste a pre-signed URL.
- **Result is HTML when you expected a file** - the URL resolved to a
  landing page. Use the direct-file URL.
