Im using ZergPool with the RX2 algo to mine LUX coin via CPU.  I'm using Awesome miner with SRBMiner-Multi.
I'm at about 95% rejected right now and I've looked around to find a solution, checking the region, NA,  check latency, less than 100ms to the pool.
 
mining Verus coin works without issues, but I know that's a different algo anything else I can check?
