Mi LED Smart Bulb losing connection

I’ve recently bought a Xiaomi Mi LED Smart Bulb, model yeelink.light.color3, and setted it up with no problems. I’ve connected it to the Mi Home app and it works, and the same goes for the integration with Alexa. My problem is that when I stop interacting with the lamp for an hour or a bit more, it loses the connection and I’m forced to turn the switch off and on. It doesn’t matter if the lamp is turned on or not, it always loses connection after I stop interacting with it. I’ve already tried to search and ask in many places, but I just don’t know what to do anymore. Can someone please help me?
