Arduino RGB Led WS2811 not working

Using Arduino LEDs and Multiplexing

Hi there,

I'm testing 1 single RGB led (WS2811, https://www.aliexpress.com/item/5-1000pcs-DC5V-Diffused-round-hat-RGB-LED-with-WS2811-chipset-inside-5mm-F5-8mm-F8/32713415299.html?spm=a2g0s.9042311.0.0.iNZlk7), but it just won't work.

I think I tried and searched enough for now, so I decided to ask here.
I tried multiple libraries (Adafruit NeoPixel & FastLED), but nothing will work. The LED just won't turn on.

Anyone has this led and can explain what I do wrong?

The only error I see (only with fastled) is:

note: #pragma message: FastLED version 3.001.006

pragma message "FastLED version 3.001.006"

I hope to see some replies.

Thanks in advance,
Remy

The controller is WS2811. The RGB LED with the controller is called a WS2812.
