Since 1-2 months my Heltec Miner does not work properly, although all updates are made directly. He has received the last Witness 21 days ago and also no longer constructs challenges. Also, the Helium explorer shows every few days that it is inactive, which can only be fixed by a restart of the miner. A reset has also brought no improvement. In the user interface everything looks normal. No error message… It seems to be, in my opinion, so some hardware defect.
