⚠️ Troubleshooting

Common Issues

ModuleNotFoundError: No module named 'tkinter'

Linux users need to install tkinter separately:

sudo apt install python3-tk      # Ubuntu/Debian
sudo dnf install python3-tkinter # Fedora
sudo pacman -S tk               # Arch Linux

Windows/macOS: Reinstall Python from python.org with tkinter enabled.

Missing Python packages

Update or reinstall dependencies:

pip install -r requirements.txt --upgrade
# or force reinstall
pip install -r requirements.txt --force-reinstall

FFmpeg not found

Install FFmpeg for video/audio merging:

• Windows: winget install ffmpeg
• macOS: brew install ffmpeg
• Linux: sudo apt install ffmpeg

Verify: ffmpeg -version

Note: CoomerDL works without FFmpeg, but video merging won't be available.

Downloads fail with 403/429 errors

• 403 Forbidden: Site requires authentication. Use Settings → Universal → Import browser cookies.
• 429 Too Many Requests: Rate limited. Lower concurrent downloads in Settings → Network.

YouTube or other site downloads fail

If you get "invalid URL" or "not supported" errors:

• Verify yt-dlp is installed: pip install -U yt-dlp
• Check network connectivity to the target site
• For video+audio merging, install FFmpeg (see installation section above)
• Try updating yt-dlp: pip install --upgrade yt-dlp
• Check the URL format - some sites require specific URL patterns

Testing yt-dlp directly:

# Test if yt-dlp can handle the URL
yt-dlp --list-formats YOUR_URL

# Download with yt-dlp directly
yt-dlp -f best YOUR_URL

Note: CoomerDL uses yt-dlp which supports 1000+ sites including YouTube, Twitter, TikTok, etc.

Application won't start or crashes

Check for common issues:

• Python version: Requires Python 3.8 or higher - check with python --version
• Missing dependencies: Run pip install -r requirements.txt to reinstall all packages
• Tkinter missing (Linux): Install with sudo apt install python3-tk
• Corrupted settings: Delete the settings file in the app data directory and restart

High memory usage or database locked

• Lower concurrent downloads in settings
• Clear completed downloads from queue
• Close other CoomerDL instances (only one should run)
• Restart the application periodically

Still Need Help?

1. Check existing issues
2. Create a new issue with:
   • Python version (python --version)
   • OS and version
   • Full error message
   • Steps to reproduce
