I'd like to use Greg Maxwell's banlist for my Bitcoin node in Windows.

When I enter the commands however, I receive the following error message for every bitcoin-cli command:

bitcoin\bin>bitcoin-cli setban ###.###.###.###/32 add 31557600 error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set. See -rpcpassword and -stdinrpcpass. Configuration file: (C:\Users\admin\AppData\Roaming\Bitcoin\bitcoin.conf)

How can I get this to work?

  • What's in your bitcoin.conf file? Did you change the data directory used by Bitcoin Core either via the -datadir option or in the GUI the first time you started it?

  • Actually the command worked now when referring to the correct bitcoin.conf file and data directory as parameters (thank you!) - however, the "setban" parameter throws a "Method not found" error message.
