SSH via keys and MFA

[uniquegch]

Hello cockpit community,
I am building a monitoring system (pi4 with two displays) and testing different monitoring tools, like grafana (not easy to use when I want to rotate the data of serveral hosts in one dashboard). I used for my SBCs cockpit within my LAN and it works great. Thank you to all the contributors.
Now I want to have my servers (by default debian based) put together, but here is the crux.
for SSH I am using different ports (that can be added after the IP for example). But I also have SSH keys in use and I enabled MFA. So my classical login is ssh nickname (details are stored in the .ssh/config) and I am getting the request to enter the verification code from the MFA app.

Log in to user@IP:ssh-port OR user@nickname results in that message
Unable to log in to user@IP:ssh-port. The host does not accept password login or any of your SSH keys.
I can login via CLi using ssh and enter the verification code.

Is there a config setting for cockpit on the server I want to connect to under

• /etc/ssh/sshd_config
• PAM configuration file at /etc/pam.d/sshd
• within cockpits config?

Thanks
