because I don't think this is a miner issue as far as non of others gpu does something even close to 100% rejected shares as
this one does and using Claymore AMD CryptoNote GPU too.
But it
doesn't with claymore for Etherum

That's the weird part of the story. I've got a consitent 44 Mh/s and shares are accepted on both gpu (testing mining rig) with Claymore Dual v10 !
https://ibb.co/c8ZX7Gthanks for the tip and replies
I will
if you are using port 14443 on cast, change this to 14444. Cast dont` suport ssl .
thanks man but it's already 14444 :"cast_xmr-vega -S xmr-eu1.nanopool.org:14444 "
