Hello,
I was using Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v11.9 in miningpoolhub
But claymore have a bug and not work in the lastest windows 10 version [Versión 1803 (April 2018 Update)]. There are a lot of people with this problem and not update to the lastest version.
Claymore's not fix this fail.
I wil chekc it several times in severals ring and all works fine in 1709 in not in 1803.
Now I have update all my ring from 1709 to 1803 and claymore not wok.
I recommend all people change the miner program.
Thanks
Roll back to 1709 and you'll be fine.
