My QNAP TS-469 Pro is no longer seen by my Roon Nucleus +

I recently reconfigured my QNAP NAS by replacing all 4 4Tb HDDs and reloading the files
The Nucleus + saw all the files and Roon behaved well.
I fiddled some settings on the QNAP and now Roon can’t see the QNAP.
My file explorer on my Windows 10 machine has access to all the files on the QNAP.
What can I do to regain access.

When I try to log in to the QNAP using \\\MusicStore, i get a message “Could not connect to share: Unuauthorized” Furthermore, the message for \\LeeperNAS\MusicStore is “Unavailable.”

This is now resolved.
