Unsupported SecurityLevel (SNMPv3) on Firepower 1140 in FDM deploy

[MaErre21325]

Hello,

i've installed two Firepower 1140 in ha running 6.6.5.2-14 version and they are managed via FDM.

I'm receiving this errors when trying to query them via SNMPv3:

%Received a report pdu from remote host: Unsupported SecurityLevel (SNMPv3)

the configuration seems ok (i've used flex config object which is the only method with fdm deploy), and can't understand what's causing the erros.
the same configuration on the old replaced asa worked fine...

do you have any tips?

Thank you

the configuration was ok, just a probe problem.
