I used Luxor and Flypool. The result in both cases was identical. So the problem is not just with Luxor. For a few days, my devices have another firmware with no problems. And you do not need to be so rude. I respect your work and I think you've done great. But your attitude towards others makes a bad impression.
  If you can make the Z9 work well with Nicehash, I'll buy a license for your Firmware.
