Hi @Nick_Knowles,
No problem - we haven’t yet configured the Tailscale and port forwarding mechanisms to talk to one another. So, when you’ve configured Tailscale correctly, Roon will often still indicate “Not Ready” in Settings.
If you open ARC itself, you should see both RoonServer and Cloud services as available and online in ARC settings.
FYI - we have work releasing into Early Access that should prevent restoring a Backup from requiring an ARC reinstall in the future.
In the meantime, I will mark your last post as a solution. Please let us know if you have any other questions.
