  • Can you edit your question to add your genesis file? Are you sure you are mining in a private network and not mainnet? Can you try launching geth with more logs enabled with --verbosity 4?

  • Your difficulty is too high I'd start with 0x200 or lower. If you modify your genesis you have to start again your blockchain to delete all previous data. To discard an ipc issue type your command mine.start(1) in the console of same instance.

  • I will start over with 0x200 difficulty so i have to delete all files data and start again, right?

  • I've deleted the 2 files inside chaindata which are "geth" & "keystore" then make difficulty 0x200 and start a new private chain using init, and start geth, open mist and attach all fine but when start.miner i get this error of coinbase: imgur.com/a/0iUskES

I think this is because you have an error about the IPC from your geth running command. (bottom left in red)

  • What will cause the error? The remixx eth address is correct what will be the problem?

  • Not 100% sure about but the --mine option is not needed to run a private miner? github.com/ethereum/go-ethereum#running-a-private-miner
