Additional Options
Fine-tune Huntarr's behavior with these additional settings:
Monitored Only
When enabled, Huntarr will only search for music that is marked as "Monitored" in Lidarr. This prevents searches for artists or albums you've intentionally unmonitored.
Skip Future Releases
When enabled, Huntarr will skip albums with future release dates. This prevents unnecessary searches for content that hasn't been released yet.
Quality Profiles
Respects Lidarr's quality profile settings. Huntarr will only search for music that meets your configured quality requirements (MP3, FLAC, etc.).
Artist Monitoring
When enabled, Huntarr will respect your artist monitoring settings in Lidarr, only searching for albums from artists you're actively monitoring.
Swaparr Integration
Enable Swaparr monitoring for this Lidarr instance to automatically clean up stalled downloads.
When to Enable Swaparr
- You frequently have stalled music downloads
- Your download queue gets clogged with failed album downloads
- You want hands-off automation for your music library
- You use public trackers where quality varies
- You download large album collections that sometimes fail
When to Be Cautious
- You use private music trackers with strict ratio requirements
- You prefer manual control over your music downloads
- You have very slow internet where downloads take a long time
- You're building ratio on specific music torrents
- You collect rare or hard-to-find music that shouldn't be removed
Troubleshooting
Common Issues
Connection Failed
If Huntarr can't connect to your Lidarr instance:
- Verify the URL is correct and includes the protocol (http/https)
- Check that the port number is correct (default: 8686)
- Ensure the API key is copied correctly from Lidarr Settings > General > Security
- Confirm Lidarr is running and accessible from Huntarr's network
- Check firewall settings if Huntarr and Lidarr are on different machines
No Missing Music Found
If Huntarr reports no missing music but you know there are gaps:
- Ensure "Monitored Only" is configured correctly for your needs
- Check that artists and albums are marked as "Monitored" in Lidarr
- Verify "Skip Future Releases" isn't preventing searches for available content
- Review your quality profile settings in both Lidarr and Huntarr
Music Indexer Rate Limiting
If you're getting rate limited by music indexers:
- Reduce the "API Cap - Hourly" setting significantly (try 100-200)
- Increase the "Sleep Duration" to 30+ minutes between cycles
- Lower the "Missing Search" and "Upgrade Search" limits to 1-2
- Music indexers are typically more restrictive than movie/TV indexers
Metadata Issues
If Huntarr isn't finding the right music:
- Verify your metadata provider settings in Lidarr (MusicBrainz, etc.)
- Check that album and artist names are correctly matched
- Review release group settings for proper album identification
- Consider adjusting search criteria for international releases
Quality and Format Issues
If Huntarr isn't finding the right audio quality:
- Verify your quality profiles support the formats you want (FLAC, MP3, etc.)
- Check that your indexers have the quality levels you're seeking
- Review cutoff settings to ensure upgrades are allowed
- Consider separate instances for different quality requirements
