hello miners, i need some help

i am trying to dual mine Eth+Sia with Claymore's Dual v10 without any overclock and i use blockchain driver for my 3xAMD vega cards.
Everything works ok for eth BUT i am getting error message for sia coins.

SC: Received error: {"jsonrpc":"2.0","id":4,"error":{"code":-32700,"message":"target-miss"}}

i use this config (i hide the last digits with "xxxx" for the post):

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal 0x52a8b69aDb6067B6a51b6Ad5d40c17F28xxxxxxx/Androxxxx/xxxxctory@hotmail.com -epsw x -dcoin sia -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal fd985fdd3278ac3afd6bea762b6ebb0408854d144e3246432d0e8ae99defe30865546xxxxxxx&worker=Androxxxx&email=xxxxxctory@hotmail.com -dpsw x -ftime 10


i can see my ETH stats at eth.nanopool.org but for SIA COINS i cannot see anything at sia.nanopool.org

i am sure that i am not the first one had this issue..
how can i solve this problem?


Thanks in advance
