Remote will not connect to Nucleus + core. Roon OS network admin settings all say "OK"

Hi Connor,
Can you please detail the steps that you recommend I try?
Thanks,
Andy

Hey @Andy_Graff,

Apologies for the delay! The Nucleus+ itself isn’t typically the cause of database corruption. Renaming the database and reinstalling the OS works because it forces Roon to create a fresh, clean database. However, if you restore from a backup that already has corruption, or if the underlying library structure has inconsistencies, the issue will return.

We recommend restoring from the oldest known good backup instead of the most recent one. If every backup seems affected, the safest approach is to start fresh and then re-import your music, allowing Roon to rebuild the database from scratch. If you need guidance on this process, we can provide detailed steps.

Hi Benjamin,
I would like more specific instructions as to what steps to take. I don’t necessarily know how to translate the concepts to specific software actions without messing it up. I don’t know what backup I would choose or how I would know if it is corrupted. I also don’t really know what you mean by corrupted. Does that mean there is a song file like a FLAC that is corrupted? Or does it mean that a file that contains meta data like genras or a playlist is corrupted? All I know is it used to work perfectly and now it doesn’t. If I were to start from scratch with a fresh database, does that mean just wiping the hard drive and re-importing music files?

Thanks,
Andy

Hey @Andy_Graff,

Thank you for following up, and I completely understand how this can be confusing. Let me clarify a few points and give you concrete steps:

What “corruption” means in this case

• It usually doesn’t mean that your music files (FLAC, MP3, etc.) themselves are damaged.
• Instead, it refers to the Roon database that stores information like playlists, genres, play counts, edits, and links between tracks and albums. If that database becomes inconsistent, Roon can behave unpredictably.

How to proceed

1. Check your backups

• Open Roon → Settings → Backups → View.
• You’ll see a list of backups with dates. Try restoring from the oldest available backup first (not the most recent).

2. Restore a backup

• From the Roon startup screen, choose Restore a Backup.
• Point it to the selected backup folder (the one with the date you chose).
• Let Roon rebuild from that backup and test stability.

3. If no backup works

• The cleanest option is to start fresh:

  • Rename or delete the current Roon database
  • When Roon restarts, it will create a new, empty database.
  • Re-add your music storage locations, and Roon will re-import your files and build a new database from scratch.

This way, your music files remain untouched, only the Roon database is reset.
