Yeelight RGB Bulb V1

Hello to everyone, I’m writing 'cause I have this issue with my led bulb, a couple of time every day is rebooting, the light will shut down and will be on again in less than a second…
I checked the voltage and I have 227volts at my place right now, the bulb is always warm, I’ve also tried to dim the light to 85% to lower the heat, but without any luck.
I’ve got the bulb working flawlessly for more than a year and only now I’m facing this problem.
I’ve got also a Yeelight RGB bulb v2 that is working without any problem.
Any suggestion?
