Hi all, when I try to mine HUSH on Suprnova pool (with 1070) I am getting following error:

Unsupported extranonce size of 16 (12 maxi)
Stratum subscribe answer id is not correct!
JSON-RPC call failed: (unknown reason)
...retry after 30 seconds

I am starting miner with command:
ccminer-x64 -a equihash -o stratum+tcp://hush.suprnova.cc:4048 -u xxx -p yyy -i 23 --cpu-priority=3 --max-temp=70

Any idea why I am getting this message?
Thank you.
