Cisco FTD1150 HA Issue

[a.aljiledi]

Hello.

I have configured 2 Cisco FTD1150 with HA from FMC ,,, the primary FTD works fine in a production environment, I have added another one as secondary but the HA status is failer,

both devices with the same model, version, snort version, and license, also the HA and state link was configured...

so how can I define the exact issue,?

Thanks

@a.aljiledi please provide the output of "show failover history"

Can you ping the peer FTD's IP addresses to confirm connectivity for each interface?

Are the FTD interfaces in the correct VLANs on the connected switches?
