500 Internal Server Error
A 500 Internal Server Error is a generic HTTP status code indicating that the server encountered an unexpected condition that prevented it from fulfilling the request. Unlike client errors (4xx), a 500 error means the problem is on the server side. The generic nature of this error makes it challenging to diagnose without access to server logs.
