Remarks

The AuthenticationException class is used to indicate errors that occur when a client and server attempt to authenticate each other. This can happen for a variety of reasons, including incorrect credentials, expired certificates, or network configuration issues.

When an authentication operation fails, an instance of AuthenticationException is typically thrown. You can catch this exception to handle authentication failures gracefully, perhaps by prompting the user for correct credentials or logging the error for later analysis.
