Hi eXtremal,

Thanks for the pool software. I found a block while running a test with your pool software but the block was not accepted by zcashd version 1.0.2, please see below and any help will be appreciated.

What miner you use? It can be some incompatibility with pool.

nobody-steem commented 7 years ago

SILENTARMY v5

eXtremal-ik7 commented 7 years ago

Thanks, v5 not tested. Problem can be on miner side (stratum implementation) or on pool side, I'll try find it in 24 hours.

nobody-steem commented 7 years ago

OK, thanks

eXtremal-ik7 commented 7 years ago

Fixed in 4f6eede67640ba80024a39ca00be00e423be7477 ! (Also this fix reduces rejected shares amount).
