Ethereum Classic Mining Pool Hubhttps://ethereum-classic.miningpoolhub.comThere was some error on ETC mining for few hours.
This problem happened only on one of the servers on europe and us-east.
As pool runs several servers, not all miners were affected.
Some were connected to wrong server and some were not.
Sorry for late, I had to dig deep to check what was causing this problem.
This kind of issue will not happen anymore.
For compensation, ETC mining fee will be 0% for three days.
Also I recommed all miners to update claymore dual miner to latest v10.2 as previous miner program can crash by remote attacker.
