Describe the issue

I rebooted my Nucleus plus 2 1/2 hours ago. I Can’t connect with my remotes, yet when I go to the IP address I can see the system status, which is all ok. This happens every time I reboot. Eventually, it returns. It continues to work very slowly, and during playback, whether through Qobuz or my NAS, it skips tracks and stalls in the middle of songs. All very frustrating

Hello @Carl_Zapp

Thank you for reaching Roon support. We have tried enabling the diagnostic on your account and reviewing the logs, but regrettably, the marked timestamp is not covered in the logs due to the rotation period.

Can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.
