Missing Root/Intermediate Certificate

This error message suggests that the Mac client device does not have the required root certificate/intermediate certificate to establish trust with the certificate authority who issued the Secure Gateway/NetScaler Gateway server certificate.

Complete the following steps to resolve this issue:

For Big Sur, please refer to Add certificates to a keychain using Keychain Access on macOS Big Sur
For Catalina, please refer to Add certificates to a keychain using Keychain Access on macOS Catalina   

The default File Format should be Certificate (.cer).
Note: You might need to rename the certificate to a .CRT extension for the client to properly identify the certificate.
