The miner has been shut down due to high-temperature protection being triggered.

Check whether the ambient temperature is too high (above 35℃).
Check whether the air inlet and outlet of the fans are blocked (for example, the air inlet and outlet are facing the wall, and there are too many attachments such as dust and catkins).
Restart at least 10 minutes after the high temperature protection, and observe whether the temperature of the miner is stable after running.
