You can only use a root CA certificate as trust for a FlashSystem grid.
User response
If a member system is using a system signed certificate, use the system root CA certificate of the member. If an externally signed system certificate is installed on a member system, provide the external root CA that has signed that certificate. In both scenarios, you can retrieve the required certificate by running thechsystemcertstore -exportrootca -scope
internal_communication on the member system.
