Hi Michael,
I'm glad you're a long time customer, and if FM is key to your business, please open a TAC case
to get this into our system for tracking. The official stance has always been to support two ZD versions
back from FM, so the older versions are not "officially" supported might be the bottom line. Perhaps
FM audit logs and ZD syslogs might be helpful to explore ZD visibility/certificate exchange, but will take
deeper investigation.
Number two, if you are using FM extensively, do you have a physical server installation of FM 9.12.2,
rather than the VM installation? I would be interested to know if the platform was in any way a factor.
Hopefully, our FM product manager might be following this thread, if they have further input. Thanks.
