For each Zixi Feeder component that has been configured in ZEN Master, you will need to configure the connection of the Zixi Feeder (using its Zixi Feeder UI) to ZEN Master. This will use the configured SSH keys to enable the actual connection. This can either be done manually by entering the configuration settings into the Zixi Feeder UI, or automatically using the ZEN tab in the Zixi Feeder UI (for v12+ Feeders).
If you are using an SSH Key that was imported from the Feeder (not generated in ZEN Master) then you will need to use the manual method to connect the Feeder to ZEN Master and not the automatic method.
Also, the automatic method requires that you login to ZEN Master using non-SSO credentials. if you don't have access to a non-SSO account in ZEN Master then you will need to use the manual method.
