Hi @master-sp,
Based on diagnostics and the model of NUC you’re using, it’s likely you’re encountering a known issue for which the team has multiple tickets in flight.
It should be possible to roll back to RoonOS 2.1 in the meantime by following these steps.
The team will keep this thread separate and hold off merging into the tracking thread (linked above) until development has confirmed a shared causal mechanism.
Thank you for your patience. We’ll gather additional logging in the meantime. Please reboot the unit once manually to upload the latest log report automatically. Thank you!
