Since the fork of the SmartCash coin there seem to be an incompatibility with the submitted shares from claymore and pool/blockchain. What we get on the pool side (and also see in claymore log) is:

2018-07-07 18:35:06 [Pool]      [smartcash] (Thread 7) Share rejected: {"job":"1d","ip":"","worker":"","difficulty":261.95348837,"error":"low difficulty share of 6.041715027996023e-7"}

2018-07-07 18:35:27 [Pool]      [smartcash] (Thread 1) Authorized :x []
2018-07-07 18:36:36 [Pool]      [smartcash] (Thread 1) Share rejected:

{"job":"21","ip":"","worker":"","difficulty":2048,"error":"low difficulty share of 5.999277894752977e-8"}

It looks like, that the difficulty of shares are somewhat interpreted wrong. This results in a reject of virtually all shares submitted and potentially caused the significant drop in hashrate that we observed after the fork.

Mining works fine using other single miners.
