RPC connection problem with the Bitcoin node on Raspberry Pi 4
As a steam junction user connected to the same router as my computer, I encountered a problem connecting it using the Python Library “Bitcoin-RPC”. The problem lies in the way the RPC connection is established.
In this article, we will examine why the RPC connection does not work and how to solve the problem using a modified approach.
problem:
While trying to connect to the parodru junction with the `Python -M BitcoinrPC, the following error message may appear:
`
Rpcconnectionerror: The connection failed (0x80040000)
`
This error usually indicates that the RPC connection is not said due to network problems. However, after a closer inspection, we notice that the router’s IP address is not properly solved by “Bitcoin-RPC”.
Solution:
To solve this problem, you need to update the code to apply a different approach to solving the IP address of the parish node.
Here is an updated version of your code:
`Python
Import bitcoin
Configure Bitcoin connection settings
rpc_user = "parad"
rpc_pass = "your_password"
Create a new Bitcoin object
Bitcoin_object = bitcoin.bitcoin ()
In this example, we create a new “Bitcoin” object using the “Bitcoin-RPC” library. Then we provide the IP address of your parodru node as the first argument of the “create_client ()method.
Alternatively, you can modify the URL of the RPC connection to attach an IP address:
Python
rpc_url = 'http: //
Replace The port number revealed by the Ubuntu server (usually 80 or 443 for HTTP).
modified code Example:
Python
Import bitcoin
Configure Bitcoin connection settings
rpc_user = "parad"
rpc_pass = "your_password"
Create a new Bitcoin object
Bitcoin_object = bitcoin.bitcoin ()
Set URL RPC to IP and PORT
rpc_url = f'http: //
to try:
Connect to the parish node with RPC
Answer = bitcoin_object.create_client (rpc_url, rpc_user, rpc_pass)
print (response.status_code)
exit: 200
except for the exception as E:
Print (e)
In this example, we have modified the URL of the “Bitcoin-RPC” connection to include IP and port address. You must properly update the code.
Application:
Modifying the URL of the RPC connection to conclude the IP address of the steam knot, you should be able to establish a successful connection using “Python -m BitcoinrPC”. If you still experience problems, make sure that the network configuration is correct and try to start the example of a modified code.
