Bitcoin: Help – Unable to Connect using Bitcoin-RPC in Python to Local Bitcoin Node

I’m happy to help you troubleshoot your issue connecting to a local Bitcoin node using the bitcoin-rpc library in Python. Here are some steps to follow and potential solutions:

Step 1: Ensure Your Machine Can Port Forward

Before attempting to connect to the Bitcoin node, ensure that your machine can port forward on port 8332 (default rpcport for Bitcoin). This is because the bitcoin-rpc client uses port 8333 for incoming connections. To do this:

• Open your router’s configuration page using a web browser (e.g.,

• If using a local Bitcoin node (i.e., not a remote one), ensure that you're using the correct RPC port (e.g., instead of

• You can also try setting therpcuser=andrpcpassword=options in your Bitcoin node's configuration file (~/.bitcoin/configon Linux or macOS, or%LOCALTIME%on Windows).

• Start the Bitcoin core daemon:./bitcoincore Daemon

• Set up a new wallet:bitcoind wallet -setregkey regkey=

To connect to your local node using thebitcoin-rpclibrary in Python, you'll need to:

• Install the required libraries:pip install bitcoin-rpc python-bitcoin

import bitcoinrpc



Set up a connection to your local node (replace  and )

conn = bitcoinrpc.Connection(url=" rpcuser="", rpcpassword="")



Perform some actions with the connection...

Note that you should replace and` with the actual values for your Bitcoin node.

Example Code

Here’s an example code snippet to get you started:

import bitcoinrpc


conn = bitcoinrpc.Connection(url=" rpcuser="", rpcpassword=""))



Get the current block number and balance

print(conn.getinfo())



Perform some actions with the connection...

Troubleshooting Tips

• If you’re still having trouble connecting, try using a different RPC port (e.g., 8334 instead of 8333) or checking your network configuration.

• Ensure that your machine is running the latest version of Bitcoin Core and its dependencies.

If none of these steps resolve your issue, please provide more details about your setup, including any error messages you’re receiving. I’ll be happy to help you troubleshoot further!
