Thank you for your patience. We run a bit behind in responding to cases but do our best to triage certain situations like yours (being down!).
I have enabled diagnostics on your account and I am seeing DB corruption in the form of fragmented records as well as the connectivity issue you described.
It may be necessary to get medieval on the problem here. Hopefully, you’ve got some solid backups from around the timeframes prior to the issues manifesting.
Here are our instructions on handling DB corruption. I’m also going to have you rename the RAAT folder when you’re looking at the Nucleus file structure.
Backup of your current Roon Database Stop RoonServer from running in
Navigate to your
Nucleus’ Database Location
Find the folder that says “RoonServer”
Rename the “RoonServer” folder to “RoonServer_old”
Find the folder that says “RAATServer”
Rename the “RAATServer” folder to “RAATServer_old”
Restart the RoonServer in the WebUI to generate a new Database
On the Roon Remotes, press “Use another Core” and connect to the new database
Try and verify whether or not things are corrected prior to restoring any backups and let me know how things go for you.
Hi Wes, thanks for the response.
Although my Nucleus is visible from the Web UI, I cannot see it in Windows Explorer so I’m unable to complete your instructions. Do you provide any type of remote support so you can get into my setup?

It might be a while before
@Wes can get back to you.
You can get to the necesssary directories by setting up a share in Explorer.
I don’t have a Nucleus. I use ROCK, but here’s how my Share looks -
The address is the address you use to get to the Web GUI.
