Authentication Against DC issue

We have admin user authentication against our DCs and we have several members authenticating correctly but on the new one, we can see in the syslog the following logs:


Connection closed by authenticating user xxxxxxx x.x.x.x. port 48476 [preauth]
Failed password for txxxxxx from x.x.x.x. pofi 48476 ssh2
Failed password for txxxxx from x.x.x.x port 48476 ssh2
2023-10-0211 [xxxxxx]: Login_Denied - - apparentlyi_via=Remote ip=x.x.x.x. auth=PAM
No authentication methods succeeded for user txxxxxx


We have also configured the communication against the DCs to be through the management interfaces and I have checked the connectivity with a ping and it is reached correctly but when we do an SSH authentication we don't see this traffic leaving the mgmt interfaces of the new member.
