FPR2110-NGFW-K9 going to block traffic

[Ataur Rahaman]

I am using "FPR2110-NGFW-K9" this firepower in my network. It was working very well but, in a day, it stopped working, that's mean it was not pass traffic throughout it. My core router is mikrotik where all IP is assigned. My network topology is:
mikrotik router>>FPR>>Layer2 manageable cisco switch>>> Cisco access switch 
Please see the attachment where I got error from FMC.

what is the Firepower IP ? Does the FMC in the same network where FTD ?

Looks like the FMC not able to reach the FTD ? please connect to FTD CLI and check all ok and device still available to reach for pings ?

Does users have internet access - what is the outcome pinging from Firepower to google ?

Firepower IP: 192.168.0.108 and FMC IP: 192.168.0.107
I can get ping each other from both device. when firepower connected with core switch and core switch connected with core router then i get ping google.com from Firepower ssh console
