Even the best 9anime.to video downloader will hit snags. Here is how to fix them:
| Error | Likely Cause | Solution |
| :--- | :--- | :--- |
| "403 Forbidden" | The site blocked your user-agent or referrer. | Add --referer "https://9anime.to/" to your yt-dlp command. |
| "Video unavailable" | The specific server (e.g., VidStream) is down. | Refresh the 9anime page and try a different server (MyCloud) before copying URL. |
| Subtitles not downloading | Subtitles are rendered as hard text in some streams. | Use the --write-auto-subs flag to fetch auto-generated captions. |
| Download stops at 99% | Network timeout or cache issue. | Restart yt-dlp with --continue (resumes partial downloads). |
