[Ticket In] B1643: Roon Server on QNAP stopped starting up after update

If you switch branch to production, after backing up your Roon database, you should be up and running again.

Once on production, disable automatic updates, since this issue will affect production later this month. Options for QNAP are discussed in other current threads.

Incidentally, you should have a backup strategy for your NAS.

You may have to uninstall the Early Access version, then install the production version. (Ensure that you have a Roon database backup)
