The. network is fine both devices are pingable to each other. I unregistered and tried to re-register with no success. it gave me an invalid or version mismatch error. I am running 6.2.2 on both FTD 2110 and Virtual FMC. Any thoughts would be appreciated.</P> Fri, 21 Feb 2020 15:01:28 GMT Gus Rosa 2020-02-21T15:01:28Z https://community.cisco.com/t5/network-security/ftd-2110-lost-conection-to-fmc-and-will-not-register/m-p/3301039#M1041443 <P>Logged into FMC this morning and noticed lost heartbeat to appliance on health status.
