Hue lights turing off

Hello. I have Hue colored lights and also Hue Lux lights. Lately I’ve been having an issue with the Lux lights either dimming or turning off by themselves. They are connected through Smartthings and I am using the auto lighting smart app to have the Lux lights turn on automatically at sunset. This happens, however, after a while they will randomly turn themselves off or dim to a low light. I cannot figure out why this is happening.

I’ve tried removing the hue bridge from Smartthings and added it and the bulbs all over again. Still having issues. I’ve also seen where it would shut all my Hue colored lights off while I was home downstairs.

What is going on?
