We have vcenter 6.5 in our main office and would like to add a remote office's ESXi host to the main office's vCenter.
I can add the ESXi host, but it shows as disconnected. I am unable to manage any vm on that remote site.
The remote ESXi host is version 6.0 and i created a separate datacenter folder.
I would appreciate your input on this.

1. Bandwidth too slow, between vCenter Server and ESXi host.

2. Firewall issues.

What happens if you click re-connect ?

Andrew,
We have a good link. I can only think of firewall.
Is there any ports (UDP/TCP) have to be open between ESxi and vCenter. I am sure the security officer is going to ask me all these?
i did reconnect and did not work.

i have checked port 902 . Firewall is not blocking it.
The ESXi host version is Essential plus and the vcenter is standard.
Can i add/manage Essential plus host with  standard vcenter?
There was a discussion way back as on the link below , i am not sure it is still true  we can not manage essential with vcenter standard.

Because of VMware Essential host.

No!

Essentials Plus is a "special starter version of vSphere", which needs to be managed by vCenter Essentials, which can only manage 3 hosts.

You will need to use at least ESXi Standard.
