After change vcenter hostname and ip error to access TsmVMwareUI

After change vcenter hostname and ip    when  i try to access a TSM Vmware Gui Web interface:

On the machine where the “Tivoli Data Protection for VMware” package is installed, open the Windows Services applet and stop the service: 
Open the file vmcliConfiguration  with notepad  (find the file in my case  on c:IBMtsmtdpvmwarewebserverusrserversveProfiletsmVmGUI) and change the name of old vcenter with the new vcenter
<vcenter_url>https://xxxx.xxx.xx/sdk</vcenter_url>
Now restart the service  “Data Protection for Vmware web Server service” and retry to connect at web interface
