ManageIQ - ERROR "A compatible version of Cockpit is not installed"

[SirAlucard91]

Hello,

When i try to reach an host from the Web Appliance, pops-up a warning that tells me "A compatible version of Cockpit is not installed" on server xxxx

This host I'm trying to reach is a vCenter, and it already has SSH enabled on standard port 22.
So I've tried to reach it via ipaddress:port or ifqdn:port but with the same error.

I've tried also adding an ESxi host instead of vcenter, with the same error.

I'm sure I'm doing something wrong, can you please help me?

Many thanks
