Midi leds turn on when I close ableton

Hi, I made my script and it works fine, no control problems, perfect led feedback, etc, but every time I close ableton all of the leds of my midi controller turns on and doesn´t turn off until I disconect the midi controller, it’s very annoying that every time I close ableton I need to disconect and conect my midi controller to turn leds off. I want to know if there´s a way to fix this. Thanks!!!
