The Director Management Console indicates "Disconnected" and "Authentication failed/SSH key error" when you view a description of the ProxySG appliance.
In this example, the appliance has an IPv4 address (10.106.17.238) and an IPv6 address (2001:380:6bf:230:2e0:81ff:fe5f:c96c). The Director configuration for this appliance has both addresses, as in the following:
This issue occurs usually because of misconfigured options on the appliance. To resolve the issue, configure the ProxySG' appliance's security settings to allow IPv6 management. Because Director connects to the appliance on both HTTPS and SSH, you must edit both services.
Edit the HTTPS Console service:
Edit the SSH Console service:
After you configure these two management services to use the IPv6 address of the appliance, log in to the Director Management Console and test access to the appliance again.
