Соло-майнинг на созданном альткоине: невозможно создать блок

Я разветвил код альткоина, чтобы поиграть с параметром и понять процесс . Источник здесь .

Теперь я хочу соло, чтобы создать блоки. Майнер находится на моем ПК, а сервер — на виртуальной машине Ubuntu 16.04. Соединение RPC работает:

http://MyUser:MyPassword@192.168.1.13:25553/    return
{"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}

но я не могу создать блок (с помощью NSG). Mycoind запускается с:

rpcallowip=*
rpcuser=MyUser
rpcpassword=MyPassword
rpcport=25553
port=25552
server=1
listen=1
gen=1
daemon=1
externalip=192.168.1.13

Но nsgminer не генерирует мне блоки, я что-то не так делаю?

С ПК:

nsgminer -o http://192.168.1.13:25553 -u MyUser -p MyPassword
