Try adding
rpcallowip=127.0.0.1
rpcallowip=192.168.*.*
when all else fails I just use what the IP is in my conf file for the computer that is hosting.... so like if the one hosting with the wallet I would us the "http://"whatever your hosting computer IP is in the home network":what ever port is for the coin
I have a feeling that won't help. I can't get cgminer to run with my conf file either. With reaper it works just fine. But then again I have never tried to set up cgminer for solo mining before. Only use it for pool mining.
My conf file:
listen=1
daemon=1
server=1
rpcallowip=10.1.1.*
rpcallowip=127.0.0.1
rpcallowip=192.168.*.*
