Hello @telosman33,
Thanks for the follow-up — glad to hear that restarting the Nucleus and adjusting the network topology resolved the playback issues 
Regarding your question about adding a Restart Roon Server button directly in the app settings:
at the moment, this functionality isn’t available in the Roon UI. As one of the community members correctly noted, the Web UI is intentionally designed to be more resilient, especially in scenarios where discovery or network communication inside the app may already be impaired.
That said, there is an existing feature request for exactly this idea, and you’re very welcome to add your vote or comments there:
At this time, product prioritization is driven largely by community demand, and this request hasn’t yet reached a level of interest that would move it higher on the roadmap — but feedback like yours absolutely helps.
Since your system is now behaving as expected, we’ll go ahead and mark this thread as resolved.
If anything changes or new questions come up, feel free to start a new topic — we’re always happy to help.
Enjoy the music
