In my test-lab, the problem was IPv6. I have these components:

 

  • ESXi 6.0U1 -host
  • vCenter 6.0U1 running on Server 2012R2 VM, top of the ESXi
  • All management components installed on that VM
  • Server 2012R2 is on workgroup, running DNS-service, static IPv4 -records to vCenter and ESXi

 

1.) Disable IPv6 -protocol from vCenter nic.

 

2.) On vCenter, create new DWORD (32-bit) value to the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\

DisabledComponents

0x20


3.) Disable IPv6 from ESXi


4.) Reboot vCenter and ESXi


After these steps it works. However, this is only workaround. Final fix seems to be create IPv6 -records to DNS.
