I'm getting a lot of issues with the Claymore miner within NiceHash in the past week, anyone else getting this?

This happens on 3 separate rigs running different cards, Furys, 280 and 390.

What often happens is periods of rejected shares even though the cards are rock solid stable and periods of disconnects/timeouts, I've tried switching regions but the same issue. If I switch miners I get no issues, but of course Claymore is the best performing.
