I was running perfect for a week or two until the latest DDoS attacks. Since then, it appears my mid-sized farm is blocked and I didn't have time to troubleshoot, so for now, I'm back at my other pool. Once things are back to normal, I'll try again.
I haven't been able to get nicehash running for a couple of days, was starting to worry the problem was on my end or something. Glad i'm not the only one, but would love to see nicehash up and running smooth again.
