I am having an issue with a hue white bulb that started to flicker and then turned itself off. It is in an overhead light with four other hue white bulbs and the others work fine. When the bulb went out it said unreachable in the hue app. I originally thought the bulb had died even though I have only had these for a week but when I went to turn the light off via Siri, the other four bulbs went off but this one light then turned on. I unscrewed it and then put it back in and it worked fine for a bit but then the issue came back. Any ideas what it could be?
