I am new at ethereum mining and I am trying to solo mine. I already installed geth and now I am trying to mine. When I go to ethereum software folder and type ethminer -G, it gives me the following error:
miner 20:17:35.189|main Getting work package... X 20:17:36.390|main Failed to submit hashrate. X 20:17:36.393|main Dynamic exception type: class jsonrpc::JsonRpcException std::exception::what: Exception -32003 : Client connector error: libcurl error: 7 -> Could not connect to http://127.0.0.1:8545
JSON-RPC problem. Probably couldn't connect. Retrying in 1...
What can be the problem?
