Rachio 3 going off and on line for the past few days

Had this guy for a few months with zero issues, now for the past two weeks I notice "schedule working offline " and open the app and its offline, check back later, its back online. I reconnect WiFi yesterday afternoon with no problems, woke up this morning and was still online and the scheduled watering was done, checked back 2 hours later(now) and I am back to offline?
