Tacx Flux S no longer connects to resistance sensors

After using my Tacx almost problem-free for a year, I can no longer connect to the resistance sensors on Zwift since this week. The power button keeps flashing red/green, which has never happened before. I've tried different power outlets, attempted to reset the Tacx, and tried downloading firmware updates, but nothing seems to help. Can anyone help me get back to training?

(P.S. My operating system is Mac)
