The firewall is disabled ... the walled was restarted after the config file was saved. I`ve tried this
ccminer -a x16s --no-gbt --no-stratum -o http://127.0.0.1:8757 -u username -p pass
but still dosen`t work!
Well it looks like solo mining is disabled for this coin. Though I'm not 100% sure because I'm mining this on a pool and haven't tried solo mining.
I, too, recommend that you try to mine this on a pool. It's quite like solo mining and the rewards (minus the pool fee) are roughly the same.
