Received SOAP response fault from []: queryConnectionInfo - A general system error occured when trying to add a ESXi Server to vCenter Server

Hi Folks,

Wondering if anyone could help me resolve this issue. I am not able to add an ESXi Host to the vcenter Server and I have tried all of the following already.

1. I have checked and verified all DNS Resolution between ESXi Server and vCenter Server and vice-versa.

2. I also replaced teh ESXi Certificate using a Windows CA generated Cert. The certificate from the browser looks good (Cert has SAN for all IP and DNS lookups)

3. Tried restarting Management Agents

Please help.

Following are the environment details

vCenter Server Version : 6.0 U2 Build 3634788

ESXi Version:

[root@esxi01:~] esxcli system version get

   Product: VMware ESXi

   Version: 6.0.0

   Build: Releasebuild-3620759

   Update: 2
