I have a HA cluster of FTD (Active/Standby). On FMC, the monitoring is complaining failures in screenshot below for the Standby FTD. Everything is healthy on the Active primary FTD and FMC... I do not see any blockings or DNS issues...Any suggestions? The Cisco Cloud Region is set as "us-east-1 (US Region)" in FMC. This happened right after i upgraded from 6.4.0.11 to 6.6.4.
