I had a similar issue when I first started mining. Turns out, it was an overheating problem due to dust buildup in the fans, even though the temp seemed fine. I gave it a good cleaning and that helped. Another thing to check is if you’re using the right power supply or have enough power to support the miner’s needs.Also, I’ve been using the Antminer S21 Plus recently, and I have to say, it’s been a solid upgrade for me. It runs smoother, has better efficiency, and I’ve had fewer shutdowns. If you’re looking to upgrade, you should definitely [buy Antminer S21 Plus]. It’s been a game-changer for my setup.
