The ESXi host can not resolve the vCenter FQDN correctly .Connect to vCenter-IP by 9084 correctly , but can not ping the vCenter-FQDN .  The ESXi host has wrong DNS server and search domain . 

 

Resolution

Set up the correct DNS server and DNS domain search by CLI

# esxcli network ip dns search --server=correct-domain-name

# esxcli network ip dns server add --server=correct-dns-server
