Two main issues here.

  1. You shouldn't mix HCX versions (you have R147 and 4.0), mixing of versions is only supported during upgrades.
  2. vSphere 5.1 is EOL and not supported for HCX. You should upgrade to at least 6.0 in order to use HCX.

I can't upgrade the version at the request of the user
I added a host with a new ESXi installation to the cluster
I have successfully deployed InterConnect on the added host.
