H100i recodnized LED Node first time but not now

Hey. So my h100i recodnized my corsair link LED node the first time, i changed some colors and had fun.

I sat it to cycle between 4 colors and after that it decided not to be able to change light color or mode. it just went trough those colors i sat.

When i turned corsair link off and on the node wasn't recognized anymore.

I've tried the following:

Reinstalled Corsair link, Tried the newest update.

both the newest and the one before.

Reconnected all cables, restarted my pc. clicked on the buttons on the LED node itself to change colors.

What is wrong?

Thanks.
