Security Engine Service State is not responding Firepower 4110

[TuanAnhBui2203]

Hi, I have an issue with cisco Firepower 4110. Firewall Security Engine Service State is not responding. We can connect to Chassis via Managment IP but FMC can not connect to FTD. Please help me to resolve this issue

Was this working previously or is it brand new and has never worked?

If it was working previously, were there any changes to the system just before it stopped working?

Sorry for late respond. I contacted with Cisco TAC and had to reset firewall to factory default, it's working.

I also have this same issue I tried factory resetting also but issue remains the same. In security engine service state is showing offline what is the service state means and what is reason for showing offline

This means that blade (which runs FTD) cannot start its operating system (SSP OS) or went into some bad state. I.e. this is most likely not a logical application (FTD) issue. You can use few FXOS commands to confirm.

! Will display all faults in the system
show fault
! "physical state" of compute blade
scope chassis 1
 show slot
 show server
! "software state" so to say
scope ssa
 scope slot 1
  show detail
  show app-instance
  show fault
! versions / upgrade status
scope system
 show firmware expand detail
