    • Review and confirm the configuration settings, then click "Configure" to apply the changes.
    • Wait for the configuration process to complete.

  4. Configure Network and Firewall Settings:

    • Ensure that the necessary ports (typically TCP 80 or TCP 443) are open in the firewall to allow incoming OCSP requests.
    • Configure DNS settings to ensure proper resolution of the OCSP responder's hostname.
