You can use the OCSP check function of your web browser to check the
revocation status of the server certificate. For details on how to check the status, see
the documentation for your browser.
For Firefox, you can check the status by using the following procedure.
-
In the settings window of Firefox, select Privacy &
Security, and then select the Query OCSP responder
servers to confirm the current validity of certificates check
box.
-
Use Firefox to access the URL for the target product, and then check whether an error
appears.
If the server certificate has expired, the
SEC_ERROR_REVOKED_CERTIFICATE error appears.
