Looks like it's not scrypt or bad pool settings. Even gnash.io is better than that. Lol
Lately I've had a lot of renters on my rigs that are clueless with the pools or settings .
Yeah my bet is that he/she is using wrong settings...
Frustrating when people just write "miner bad plz fix"
Its a pool error. The Pool Diff is to low.
Your 1 Miner is more than all of the miners currently on the pool if that says anything about how small the pool is.
