What Does RPC Mean?

Remote Procedure Call (RPC) is a protocol that allows one program to request a service from a program on another computer across a network. In simpler terms, it enables different software components to communicate seamlessly, whether they are on the same machine or distributed across multiple systems.

What is the Cause of RPC Error?

RPC errors can occur for several reasons, including but not limited to:

1. Network Issues: Connectivity problems can prevent effective communication between different systems or services.
2. Firewall Restrictions: Security settings might block RPC requests.
3. Server Overload: The RPC server may be overloaded and unable to handle more requests.
4. Incorrect Configuration: Misconfigured settings on the server or client can also lead to RPC errors.
5. Service Malfunction: Sometimes, the RPC services themselves may be faulty or not running.
