Hi guys.. I have a problem here and I hope you guys can give some advice. I just installed my M20s 4 days ago... it was running fine at first but after around 14 hours to 16 hours... it fluctuates and the hashrate keeps dropping and on and off by itself a few hours and then it runs again... it has been like this for these few days already. Sometimes it shut down and I reboot it to start again. Anyone facing this problem before? Or am I unlucky to get a faulty miner
