Why “verification failure” during solo mining at windows

Why “verification failure” during solo mining at windows?

start bat:
wownerod.exe --start-mining xxxxxx --spendkey xxxxxxx

you might get the message when there is a reorg and blocks of an alternative chain are rejected or something is wrong with the data in the block.

Thank you for your reply. and i want to know how to fix it, or will it affect mining?

you can ignore it if it is not the block you mined.

How can I know if I mine this block. The wonerod windows will display?

you will see a big wownero logo
