I'm having problems with Ant miner S9.
in miner on the minerstatus tag announces hashrate is 13.5TH but on the Dasboard pool only 10TH or 11TH announcement (there are some 14TH). (VIABTC or BTC.COM is same).
I have about 100, whether I exploit ViaBTc or BTC.com also have this case.
I want to know why that happens, and how to fix it. Or is this normal? Please explain it to me.
