Reject reason : code:-1 data: message:duplicate share
I used the latest version of miningcore 64.0.1.0 with geth 1.12 stable.

i see somethimes these in den mining window:

...
14:58:19 miner Reject reason : code:-1 data: message:duplicate share
14:58:19 miner **Rejected   25 ms. x.x.x.x:4073
...

what this means?

do geth/miningcore/miner software work all fine?

do miningcore or geth rejected the share?
