Bitcoin Core RPC Server does not work: Problem Guide
Do you experience trouble connecting to the RPC Bitcoin Core (BTC) server? If this is the case, this article will guide you to a detailed guide to solving problems to help solve the problem.
What is the RPC server?
The RPC server is a critical part of the bitcoin core. It allows the node to communicate with each other and, among other things, facilitates transactions. In this section, we will examine why your node may not respond to connections.
common problems:
Before diving, we will cover some common problems that may cause RPC to work:
* Ports conflicts : Make sure no additional bitcoin nodes or services use Port 8333.
* network problems : Make sure you are connected to a stable Internet connection. If your connection is slow or unstable, it can affect the nodes communication.
* Node configuration problems : Double check that your node configuration file (eg “Node.conf) is correctly set and configured.
Steps to solve problems:
- Reboot the knot : Sometimes simply restarting the knot can solve the connection problems. This may be the easiest repair, but it is necessary to try all the other options.
- Check the network connection : Verify that you are connected to your Internet Services Provider (ISP) and whether your network connection is stable.

Try a different port : If you have more bitcoin nuclear nodes or services on different ports, try to connect to them using the "http instead of” RPC “. For example: http: // exemple.com/bitcoincore.
- Verification of nodes configuration : Make sure your node configuration file is correctly set and configured:
* Open the terminal and start node.conf -c
* Check any errors or warnings regarding the RPC Server Configuration.
- Disable RPC server : try temporarily disable RPC server (if permitted) by setting the symptom
rpcenabledin the node configuration file (node.conf)::
`
rpcenabled = false
`
- Check logs : Check logs for not any error messages relating to the RPC server:
* Check Bitcoin Core Node log files: /VAR/LOG/BITCOIN/Core.log (Na Linux) or%logfile%(in Windows).
- Bitcoin core update : Make sure you operate the latest version of the bitcoin core. You can update from the node using the “Bitcoin-QT update” or
bitcoin-core update.
Next steps:
If none of these steps will solve the problem, it is possible that there is a basic problem with a node configuration or software setting:
- Check the conflicts between different bitcoin core modules (eg "Bitcoincore,
Bip32etc.).
- Verify that your node uses the correct version of the blockchain.
- Consider finding help from the Bitcoin Basic Forum or Support Group.
Conclusion:
If you have followed these problems to solve problems and still encounter problems connecting to your RPC server, it is likely that this is a problem specific to the node configuration or software setting. We recommend that you check the protocols, update the bitcoin core and verify that all necessary services are working properly. If the problem persists, consider seeking additional help from a qualified developer or a bitcoin support expert.
