Description of Issue

I’m unable to rebuild my Roon ROCK Library. The library build process fails partway through the process with a possible corrupt database and then loses its connection with the Core. The remote tries to reestablish its connection but fails with a “Something when wrong” message, followed by a “Lost Connection” message.

I tried to select another core to restart the process but was presented with an empty “Select Your Audio Devices” page. I clicked finish and was presented with the initial Library build page with all Artists, Albums, Tracks, and Composers values zeroed out and a progress spinner. After no additional activity was detected, I closed the remote, zipped the Logs folder, and uploaded the zipped folder to your Logs Upload Server for your review.

I’ve tried this process several times and received the same built process failure results. Please review the Logs and let me know if you can identify what I need to do to get everything working again.

What follows are screenshots documenting the sequence of events I encountered.

Started the latest Win10 Remote Client
Selected my NAS Network Share for Music
Logged onto Tidal
Landed on this page

Enabled Benchmark 1.0 and SXFi Amp devices
Clicked Finish to start the Library build process - Adding 68335 tracks

The process went up to 8863 tracks / 741 albums
Then shortly after, received a Waiting for your Roon Core message

Clicked Finish
Then the process appears to start over

After a few more minutes of no activity, I closed the Client to view the Logs
I zipped Logs folder to Larry_Logs2.zip and uploaded the zipped file to your Logs Upload Server.

Before signing in to the newly built Roon core (ROCK), you can click on the “Restore from backup” link at the bottom of the screen.

Since you’ve already signed in, skip the setup steps, and go to Roon Settings > Backups, and restore a recent backup made before rebuilding ROCK.

Incidently, the “Waiting for Roon Core” message does not necessarily mean that the core is offline; rather, Roon remote has lost the connection. You can check that the core is online using a web browser: http://rock.local. If this doesn’t connect, check your network connection.

I was unable to get “Restore from backup” to work. I started the Remote and clicked on Find my Remote Core.

It took 5 minutes to find the Core.

I clicked on restore a backup and the backup started.

After another 10 mins. I received a Waiting for remote core message.

Then was thrown back to the “Restore a backup” page.

The Core was running the whole time.

What could be causing the Remote to lose its connection? I’ve ordered new Cat8 cables and a new TP-Link switch to eliminate those as an issue.

Were you able to identify any issues that appeared in the logs that I uploaded?

@Larry - If you get that corrupt database message more than likely you won’t be able to restore from that specific backup. If you made other backups, I would try restoring from those to see what happens. I’ve run into this before and had to restore from a different backup.

Thanks for the suggestion @TheRiz. That was my thought as well, so I tried another bkup and ran into a similar Remote Connection issue which is why I ordered the new switch and cables to address a potential network connection issue. I’ve also recycled all of my devices from the modem to the remote to no avail. I thought rebuilding the system from scratch would be an easier solution, but that has not been the case.

@mjw Quick update… It’s ALIVE!

The new switch and cables arrived today. After swapping out the new equipment the restore backup process completed successfully! The problem could be related to a failing switch. Recently we had 4 or 5 power fluctuations in a 20 minute period.
