Firepower 2120 chassis manager https access refused

[gaigl]

Hello,

we've a few Firepower 2120 and 2110, and for snmp-monitoring, we want to activate the https access to the FXOS.

on 2 2110 everything's fine, but the 2 2120 I can connect via ssh but not https:

the https port is correct and enabled

the fabric-interconnect have the correct IP, Gateway, Mask, the ip-block looks now like

Permitted IP Block:
    IP Address      Prefix Length Protocol
    --------------- ------------- --------
    0.0.0.0                     0 https
    0.0.0.0                     0 snmp
    0.0.0.0                     0 ssh

I've compared a lot of settings of the working 2110 with the non working 2120, but can't find a difference, version is:

a check with curl says: connection refused

Any Ideas?

Can you check if these appliances are configured to run in "Appliance Mode?" If yes, the FXOS chassis manager is not supported.

they are all in Platform Mode

Hmm, in that case I suggest you open a TAC case to have this further investigated...unless one of the community experts here can give additional guidance.
