Ran into the issue again just now. Filed a feedback report FB16000502

Thanks for the insight, last night I was facing this issue and indeed it was extremely frustrating. Closing xcode did not help "reset" anything. However, turning off the Mac did work. Next time I am in the middle of a dev session and my watch refuses to connect, I will grab logs as you have guided. FWIW, I do triage work for the other side... Dealing with these kind of intermittent failures is quite a nightmare in the triage world. Also, AFAIK, there are no exact repro steps.... Something goes stale and connections are refused. By reset, I mean the problem went away automagically. Tuning off/on the watch doesnt reset Tuning off/on xcode doesnt reset Turning off Mac did reset (M1 Air 2020)
