When I try connect to suprnova with gominer, I get the following error: POOL: read tcp 192.168.1.101:54501->178.33.228.14:2252: wsarecv: An existing connection was forcibly closed by the remote host. My command is gominer.exe -m user.minername-n minerpwd -o stratum+tcp://dcr.suprnova.cc:2252 -D 1 Any help diagnosing this issue?
