Problem with RPC and Bitcoin node and Raspberry Pi 4 Connecting a problem
Because the roofing node user is connected to the same router as my computer, I encountered a problem that has joined the Python Library “Bitcoin-RPC”. The problem lies in creating an RPC connection.
In this article, we examine why the RPC connection does not work and how to solve the problem with a modified approach.
Problem:
When you try to connect to the umbrella node using “Python -M Bitcoinrpc”, the following error message may occur:
`
RPCCONNEBORROR: The connection failed (0x80040000)
`
This error usually indicates that the RPC connection fails due to network problems. However, after closer inspection, it is noted that the IP address of the router is not properly solved by “Bitcoin-RPC”.
Solution:
To solve the problem, you need to update the code to use different access to solve the umbrella node address.
Here is the updated version of the code:
`Python
Import Bitcoin
Set up your Bitcoin connection settings
rpc_user = ‘umbrella’
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” directory. Then we hand over the node’s IP address like the first argument of Create_client ().
Alternatively, you can set RPC URL to IP:
Python
rpc_url = ‘http: //
`
Replace the actual IP address of the casing node and the '. Replace the port number exposed to the Ubuntu server (usually 80 or 443 for http).
The modified code is an example:
`Python
Import Bitcoin
Set up your Bitcoin connection settings
rpc_user = ‘umbrella’
rpc_pass = ‘your_password’
Create a new bitcoin object
Bitcoin_object = bitcoin.bitcoin ()
Set URL RPC to contain IP address and port
rpc_url = f’http: //
try:
Connect to an umbrella node using RPC
Reply = Bitcoin_object.create_Client (rpc_url, rpc_user, rpc_pass)
Print (respect.status_code)
output: 200
In addition to the exception E:
Print (E)
`
In this example, we edited the Bitcoin-RPC connection URL to contain IP and port address. You must update the code accordingly.
Conclusion:
By setting the URL of the RPC connection by containing the umbrella node IP address, it must be able to establish a successful connection using “Python -M BitcoinRPC”. If you continue to experience problems, check that the network configuration is correct and try to start an example of a modified code.
