How to setup Host and vCenter to use FQDN instead of IP Address?

  • 1.  How to setup Host and vCenter to use FQDN instead of IP Address?

    Hello everyone,

    My environment is as below

    1/ Installed VMware ESXi v.7 on a standalone server, IP Address (for the purpose of demonstration) is 10.10.0.100

    2/ On this ESXi server, I created a virtual machine for Windows Server 2019 serve as Active Directory and DNS Server, IP address 10.10.0.101. Primary DNS server's address is set to itself (10.10.0.101). Secondary DNS is my Pi-Hole, address 10.10.0.254. The Domain Name of this WS 2019 is testhomelab.com

    3/ Created DNS forward lookup point to the ESXi Host above (e.g. 10.10.0.100) using the name "TestVCSA" --> the FQDN of this host is then "TestVCSA.testhomelab.com"

    4/ I want to install vCenter Server Appliance to the Host above, but instead of using IP Address, in this case, I assign static IP address of the vCenter is 10.10.0.109 

    My issues: 

    In the "vCenter Server deployment target" --> I put "TestVCSA.testhomelab.com" --> it said "Failed to get an SSL thumbprint of the target server certificate." But if I put the IP address of the host, e.g. 10.10.0.100 --> It is OK to proceed. So, I was thinking is there some kind of firewall or group policy in the Windows Server 2019 that I need to modify in order for the VCSA installation recognize the FQDN of the Host?

    Or do I need a Windows server 2019 seaparated on a different server (not the same as the ESXi host) to do this?

    The log said

    2021-08-23T03:43:40.648Z - debug: wizardTitle: Install - Stage 1: Deploy vCenter Server
    2021-08-23T03:44:04.559Z - error: Could not get certificate fingerprint from host: TestVCSA.testhomelab.com. Error: connect ECONNREFUSED 52.128.23.153:443

    And I have no idea of for whose the Ip addres  52.128.23.153 (above)

    How do I re-config the Host and vCenter so they will be recognized by FQDN?

    Am I missing something here?

    Update ur ESXi hostname/DNS/DNS suffix on DCUI . Make sure the DNS had this entry already. Create a new entry for vcsa fqdn even
