Apologies 100% if this has been asked and answered... I did dig around through quite a few of these pages before posting.

Is there an issue with these units and Nicehash? I've tried unsuccessfully all day today to switch the pool to Nicehash, and it immediately goes to an inactive status. I can put it on any other pool and it immediately begins hashing (Sigmapool, Litecoinpool, etc.) with no issues.

Thanks in advance...
