I tried to run it on another rig and it has updated well .
JSON.config gets null parameters...
Maybe OS can not generate correct key from motherboard?

I checked but i cant debug it.
Did you tied reboot or changing options ?
If still not i can connect via team viewer to anyw widnows that is in the same network as miner, and can debug whats happening.
