Brand new Unraid user here..be gentle. Yesterday i setup the latest Unraid 7.2.3 on a PC, worked fine. I setup the attached RTX 4060TI with the nvidia driver app using latest 590 drivers and also the gpu statistics app. Everything worked fine. I powered down the server disconnected monitors and moved the box to another area headless and now when i check the driver 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. I get the same in terminal, I system devices i see the following..Where else can i look or what info can i provide. My nest step will be to reconnect the monito and see what that does..
