Yeelight ChuXin A2001 C450 (2.0.6_0003) Home Assistant Unavaliability

Hi! I have Yeelight ChuXin A2001 C450 (fw_2.0.6_0003). Problems started in the assistant’s house: when turned on, the lamp appears in the app, but after a while (from a few minutes to 4-5 hours) it falls off. The following entry appears in the Home Assistant logs:
ERROR (SyncWorker_32) [homeassistant.components.yeelight] Unable to update device 192.168.XX.XX, [name]: Bulb closed the connection…

After the lamp is physically turned off and turned on, they are available again in the Home Assistant for a while/

Sometimes the lamps fall off synchronously, sometimes in turn - I didn’t find any connection. At the same time, in the Yeelight app, the lamps are accessible and controlled.

Please help with the solution. Thanks!
