If you disable the Yolink integration/drivers, do things improve? Or have there been other recent additions or changes to your Hubitat system recently?
One of the challenges I’ve seen with Hubitat’s app/driver/networking implementation is sometimes an app or driver can start to overload the system and while it’s not always immediately apparent that there’s an issue, it will start to surface as issues with the networking stack in Hubitat. Something of a “canary in the coalmine” for bigger issues.
