Did you try a different pool?
Nicehash has a lot of issues with a lot of gear.
L3++
is not an L3+
so the issue could be nicehash not the miner.
yes i tried the antpool too
what do you mean the l3++ is not the l3+? ye i know they are different machines but did you see anything unusual that i did?
I can see by the photo that you may have a firmware issue.
