Error message when try to connect to STM32L476RG NUCLEO via STM32CubeProgrammer

Hi everyone,

I try to connect to my NUCLEO board (NUCLEO-L476RG) via STM32CubeProgrammer but I receive the following error message:

I reinstalled the STM32CubeProgrammer but nothing changed. I used to write my program to the MCU flash several times using Copy/Paste .bin file directly to the following storage before:

but I am not enable to program the MCU via STM32CubeProgrammer. Even I am not able to use Copy/Paste to program the MCU anymore.

This is my NUCLEO development board: (NUCLEO-L476RG)

Does anyone have any solution please?

Thanks

Does the correct voltage show up?

Try holding BOOT0 during reset, then connecting.

If you remove connections to other things, does it work?
