i m using Vcenter server version 220.127.116.11000 and trying to add ESXI server with Version 18.104.22.16806603.
The ESXI Server addition keeps failing, i tried to ping the ESXi server from Vcenter CLI and it was failing as well. I thought its network reachability issue, but when we enter the ESXi server hostname and credentials, ESXI responses with Cert Fingerprint.
Following the TASK TAB, below is the message: The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding.
while I was reviewing the TASK tab with details, I noticed that it was throwing credential errors, I was using a root user account for integrating Vcenter with ESXi server. I verified by login to ESXi using the root account again.
Using same Vcenter version of Server I m able to add ESXi 6.5 host and it works without issue. But with ESXi 6.7 it seems there is some level of firewall rule that needs to be ticked off.
appreciate your support.

Well, there's your issue. If you cannot ping the management vmkernel port from the vCSA, you have firewalls in the way or other network-related obstructions. You'll need to figure out which case in your own network.
