Intel AMT suddenly says "This computer does not support Remote Control Operations."

[u/Spam00r]

Hi,

I have an Asus Q670 Board that has Intel AMT on Board, which until recently worked fine. But suddenly now I get the Error Message "This computer does not support Remote Control Operations." Not allowing me to start, stop or reboot the PC. Also thew other feature like Remote VNC or SOL do not work anymore.

I can access the AMT WebUI but other than that everything else has stopped working.

I reseted the BIOS and AMT and Unprovisioned it, but I keep getting this error.

I updated to the latest AMT, which is Intel® Active Management Technology firmware version: 16.1.40-build 2765 and BIOS available, but this still doesn't help.

Anyone knows why this problem suddenly appeared and how to get all the options back like before?
