I have not been mining Stellite for some time now, but gave it a quick test on the 3 pools I've used..

https://cryptoknight.cc/stellite/#
https://xtl.cryptopool.space/en/#/home
https://communitypool.stellite.cash/#/home

..and found that the only one that now works (others gave error "..found incorrect share.") is the CommunityPool , strange ?

There may have been a fork and the CommunityPool is on the old chain.
