That doesn't solve the problem, it's just a work around of some type, this firmware seems to be sketchy, why do you need to use their website to mine with your own gear? your kernel log shows the miner is working without any issue, it was supposed to hash at full speed on btc.com, even on Nicehash, I would change this shitty firmware if I were you, just use the default multi-option firmware by Bitmain.
