Yeelight bulb randomly goes on and off

I have a Yeelight Bulb and with the latest firmware, it randomly goes on and off.

Once I have turned it on, it goes off at completely random time and after that it becomes unresponsive from the Android app, so I can’t turn it on again.

My MID ID is 1655344743.

Please inform me about the issue and ensure me that no other person has access to my account.

Which server do you connect? Please confirm that if the device shows offline from Yeelight and Mihome when this happens again?
