I'm mining second coin on NiceHash. In one moment profitable is B2S, in other Keccak.
On April 12 began troubles with keccak, 100% shares rejected. Error example:
12:57:12:601 bff7700 buf: {"id":13,"result":false,"error":[1,"Share above target.",null]}
It jump from normal mining to total rejects
https://ibb.co/eYNYrnHow to fix this?
