This issue may be caused by an out-of-date intermediate certificate installed at NetScaler Gateway. This does not mean that the CA certificates currently being used is expired but the CA has since released newer versions of that certificate.

Verify the certificate bindings at the NetScaler Gateway to resolve this issue.

To confirm this, visit the NetScaler Gateway website using a web browser, and examine the certificate chain in the web browser. You may wish to cross-check this by repeating with more than one web browser (such as with Google Chrome and Mozilla Firefox). Then, compare all the certificates in the browser's certificate chain with the certificate chain at NetScaler Gateway.

Note: Compare all the serial numbers in the certificates and not just the Subject Name. If there are any mismatches in intermediate certificates, this is a possible cause.

For more information about installing and linking an intermediate certificate with Primary CA on a NetScaler Gateway appliance, refer to CTX114146.

Problem Cause

The Receiver for Windows 4.7, Receiver for Mac 12.5, Receiver for Linux 13.6 and newer versions are going to validate the root certificates even if it trusts the intermediate, which is not the case with the browsers. If the browser trusts the intermediate, it trusts the server certificate, without going down to the root certificate and will display the newer version of the root from its certificate store and not the actual root certificate sent by the server or NetScaler Gateway.
In Receiver for Android 3.12.2, joint server certificate validation is turned off by default. If this policy is enabled in the Receiver without the correct set of certificates configured on the server/gateway, users may see the error message.
