nah thats bullshit, ive seen that again & again. its just a standard excuse (blame game) that no-one has proven fake yet
yes, logged into it. adjusted the pool data etc. but nothing is coming out on the pool
Fill in 1 pool info, leave the other 2 pool info empty, save everything.
Fill in second pool info, leave the third pool info empty, save.
And finally fill in the last pool info.
It's sound weird to do it like this, but it works on some Antminers who can't save the pool info in 1 time.
Most of the people only use 1 pool, no failover, so they won't notice there is a small bug in the software of the Antminer.
