I just installed a NVidia Quadro 4000 in my UnRAID server. When I try to configure it in the setting, I get:

"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."

Nvidia Driver Version:  440.59

 

But the card is detected by the OS.

lspci -v
