FMC: Smart Agent communication error with Smart Licensing Cloud

swscco001
Level 3
Level 3

Hello everybody,

our customer has two FPR 2110 running rel. 6.6.0 managed by
FMCv running rel. 6.6.5.2.

In the health monitor he see the error message for the FMC:

Critical Modules:1,Warning Modules:1,Normal Modules:25,Disabled Modules:15
ModuleSmart License Monitor: Smart Agent communication error with Smart Licensing Cloud
Smart License Authorization expired
(see attached screen dump)

There is currenlty no licencing issue (see attached screen dump).

I found the Field Notice:
https://www.cisco.com/c/en/us/support/docs/field-notices/721/fn72103.html
but the customer has already a fixed FMC release.

The FMC can reach tools.cisco.com:

root@FPR-Mgmt:/Volume/home/admin# ping tools.cisco.com

    -         1) Go into expert mode in the FMCv
               2) Issue the command "sudo su -"
               3) Issue the command "rm /etc/sf/gch/call_home_ca"
               4) Issue the command " "pmtool restartbyid sla"
               5) Issue the command "pmtool restartbyid CloudAgent"
               6) Try to register the FMCv again.

Hi Marce1000,

thanks for your fast reply!

I follow your small guide in the expert mode and got no error message:

> expert
admin@FPR-Mgmt:~$ sudo su -

Last login: Wed Aug 14 08:11:54 UTC 2024 on ttyp0
root@FPR-Mgmt:~# rm /etc/sf/gch/call_home_ca
root@FPR-Mgmt:~# pmtool restartbyid sla
root@FPR-Mgmt:~# pmtool restartbyid CloudAgent
root@FPR-Mgmt:~#

Then I unregistered and tried to register the FMC again with a new generated token, but I could not regiter the FMC again.

I see the error message :
ErrorFailed to send the message to the server. Please verify the DNS Server/HTTP Proxy settings.
(see attached screen dump)

I also tried the previous token - same result.

The FMC is indicated in the Smart Software Licensing with all services.

What can I do to get the registration working again?

Thanks a lot!

Hi marce1000,

I don't see an error in the curls, nslookup and dig command.

I also checked the Firepower event log for any BLOCKs but there was nothing.

What would you do in this situation to get the registration working again?

Thanks a lot!

  - Everything seems to work from (curl) ; could you also examine in native mode (meaning when the FMCv has effectively tried to communicate with the license server , examine (from expert mode) :
                                       /var/log/httpd/httpsd_error_log
                                            /var/log/process_stdout.log
                                           /var/log/action_queue.log
