hi
I recently got a Cluster HAT v2.4 and so far it worked well.
The Raspberry Pi Zeros and the PI 3b + that I used for it
also worked without problems.
But since 2-3 days ,the Zeros are no longer displayed in the network.
The first thing I suspected was the operating system of the Zeros, but they boot up without any problem.
I also see the Pi 3 B + and can access it as ususal.
I replaced the USB cable that came with it, but nothing.
if someone could help me with this. That would be great.
Sorry for my bad english.
