Mi-led ceiling light Alexa compatibility

Can anybody help me please?? I’ve wrotten to all yeelight pages in chinese as well. For two years my ceiling lighr was working fine and now for some time Alexa says the server is unresponsive and cannot use the light. In yeelight app it works normally only with Alexa doesnt work. Tried reinstalling one million times and nothin. My problem is I bought the light specifically foe Alexa voice skills because manual switch is built behind piece of furtinure that cannot be moved soits very important to fix it or I cannot use the light
