You’ve posted in the technical support forums, but we can tag the @accounts to take a closer look. If you navigate to the Accounts page and sign ih there, you should see the current status of your account.
I checked your account diagnostics and it looks like your ROCK is online and working as expected. Does this issue happen from a MacOS remote?
Can you please navigate to macOS System Settings > Privacy & Security > Local Network , and make sure Roon is allowed. If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.
