[nanotec]

hi,
 I want solo mining with my ASIC KNC Titan with bfgminer. The wallet is synchroniced. I can solo mine with my computer and a graphic card but not with the ASIC.
What is the problem ?

The config in the wallet:

daemon=1
listen=1
server=1
rpcuser=x
rpcpassword=x
rpcallowip=192.x.x.x
rpcport=6579
gen=0
addnode:.....

The ASIC config

 http://192.x.x.x:6579 , user and password

Thank you for your answer.
