Yeelight schedule doesnt work

I am having a problem with my yeelight schedule that it doesnt work so many times. However, if i try to make a dummy schedule to test it will work properly, but it doesnt work if I set the schedule to ON around sunset and OFF around sunrise. The connection on the bulb is very stable. I dont know what is wrong causing this problem. Anyone can help?
