I was solo mining with my own wallet at stratum.solo.nicehash.com:3334...
But the block was not solved for ages after this message, and finally was relayed by AntPool eventually...
That's not wallet mining. With pool mining you have to wait until the block matures then the block minus fee will be sent to
the specified address in your wallet. However, there should be a record of the find in your user stats at Nicehash.
You should probably take it up with Nicehash support.
