¶ºÒõ¹Ý

On September 30, 2015, at 12:15 pm, a legacy and long unused ¶ºÒõ¹Ý cross-signed certificate expired, causing some users to experience untrusted certificate errors.

The problem is generally related to a locally installed legacy intermediate certificate that is no longer used and no longer required. The problem mayÌýaffect any client platform with a locally cached or installed copy of the expired intermediate certificate.

Information about the Expired Legacy Intermediate Certificate

The expired certificate in question is the "¶ºÒõ¹Ý High Assurance EV Root CA" [Expiration September 30, 2015] certificate. This temporary intermediate certificate was used in years past as part of a compatibility chain for older devices.

Is the Expired Intermediate Certificate on the Server- or Browser-Side?

To determine where the error is occurring, use ¶ºÒõ¹Ý SSL Installation Diagnostic Tool. Type in the name of your server and click Check Server. If the cross-signed intermediate certificate (expiring September 30, 2015) shows up in the certificate chain, then the problem is on the server side. If there is no intermediate certificate in the chain, then the problem is on the browser/client side.
