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 have 22 l3+
I have a few l3
I can see by the photo that you may have a firmware issue. try changing the names of your workers.
btcaddress.l3++ make it btc address.l3a
btcaddress.l3+++ make it btc address.l3b
btcddress.l3++++ make it btcaddress.l3c
I think the firmware can't handle the + signs
