Code:

error: get_temp_info: read temp sensor failed

its bad sign, its mean motherboard or hash board are defective, captor dont give temperature...

Not really, there Kernel log is not a holly book, the problem is not seldom stated explicitly in the kernel, i have a few miners that have the temp-sensor failed problem and they work without an issue.

OP, use common sense, if the problem happens to more than one miner then it can't be cables, wires, etc.. it has to be something they all have in common, which is one of three.

1- Voltage
2- Internet
3-Firmware

Given that they are T17s, these gears have almost zero tolerance to voltage drop, if you are not feeding them stable 200-240v, they will act funny, the reason why one will fail when another one does not, could be because the voltage regulates / increase when one miner goes out of the equation.

I can go on and on explaining all different possible, but to make your life easier, try to shut down half of them, keep half running, if the problem goes away, then it's your voltage/internet, if not then try a different firmware. It can't be anything but that.
