I do not manage to mine it in solitarily, who is the rpc? Thank you I wait for his response
You can choose any port what you want. For example i've chosen 9382 (just replace the asterisks "rpcport=****") so in ccminer my .bat file looks like:
ccminer-x64.exe -a scrypt -o http://127.0.0.1:9382 -u * -p *
