The error message you encountered indicates a connection issue occurred while attempting Raft protocol client communication. Specifically, the error message “connection aborted” means that after the client tried to establish a connection, it was actively closed by the other party. This could be due to various reasons, including but not limited to:

  • The target server is not listening for connections at the specified address and port.
  • Network issues prevented the connection request from reaching the target server.
  • Firewall or security settings on the target server blocked the connection request.
  • The application on the target server rejected the connection request.

To resolve this issue, you can take the following steps:

  • Confirm whether the address and port of the target server are correct, and whether the server is running and listening on that port.
  • Check if the network connection is normal, ensuring there are no network failures or configuration errors.
  • Check the firewall or security settings on the target server to ensure they allow connection requests from the client.
  • If the server application is responsible for handling Raft protocol communication, check the application’s log files to determine if there are detailed messages about the connection rejection.
