I found in the event log that it appears that events are being blocked between the FTD and FMC. I'm not sure how to resolve this as I can't push an AC policy change to the FTD. I can Ping and SSH to both FTDs and the FMC.</P> Fri, 21 Feb 2020 17:12:29 GMT https://community.cisco.com/t5/network-security/ftd-cannot-communicate-with-fmc/m-p/3871125#M923305 jmartin@mooresvillenc.gov 2020-02-21T17:12:29Z https://community.cisco.com/t5/network-security/ftd-cannot-communicate-with-fmc/m-p/3871334#M923306 <P>Hi,</P><P>Do you have&nbsp; a TAC Case logged for this? What did you upgrade first? FMC or FTD?
