UNfortunately I already try since it was the reason for me to put all my D3 with Blissz firmware - it didn't fix the issue either.
so you had this issue on the bitmain firmware also?
if so, the only thing left for me to assume is that you have bad hashboards. typically this is the answer if you have individual boards go missing from the miner status screen. for most people a simple reboot or firmware reset will fix it, however if youve already done that, i think you may have hardware damage. if you ordered them all in the same batch its possible you got a bad batch, or if they run hot in your location that could also accelerate damage.
