do you also have AwesomeMiner software running? There could be a random rule causing that.
I don't want to get too confident, but I believe this just saved me so much stress and lost money. I have been mining for the past two hours flawlessly.
It was working with Braiins OS, but for whatever reason Braiins never detects as many hashboards as AwesomeMiner/Vnish
I believe the issue was with the AwesomeMiner software on my PC on the network. If I fully quit out of the software and rebooted the miner it would work flawlessly, but as soon as I opened up the software again the same issue would occur. I tried re installing the software, but that made no difference. For now I have fully removed the software from my PC.
I really hope this solution lasts. Thank you so much for you comment!
