Every Bulb in my house is uncontrollable since recently (Cree, Osram)

With no modification to any smartapp or DTH in hub, every light bulb in my house is now uncontrollable. Is something going on that I’m unaware? I found this guy who has the answer to switch the DTH, and still no luck:

Sorry. Have not had any problems with my Cree bulbs. Please open a ticket with support by calling them directly.
