If your ProxySG appliance is configured to intercept HTTPS traffic, you may see cases where the proxy presents the exception: "Expired SSL Server Certificate" and the following default error message:
Expired SSL Server Certificate (ssl_server_cert_expired)
Your request contacted a host which presented an expired or Invalid certificate
This is typically caused by a Web Site presenting an incorrect or invalid certificate, but could be because of a configuration error.
For assistance, contact your network support team.
