HomeKit keeps loosing sync

Every once in a while I go to use HomeKit and all my devices say “no response”. Most of the time I can just restart the HomeKit integration from the HomeKit page. But sometimes I have to reboot the Hubitat to get it working again. Anyone have any thoughts as to why?

I have the exact same issue.
The thing I found in my case: This only occures when Homekit has switched over from node. (apple-tv to homepod, or apple-tv to apple-tv)
If I failover back, or reboot HE, it starts working again.

How do you failover back? I have 3 HomePod minis and I never paid attention if it changed nodes when it happens. But I will now.
