Thanks all for jumping and help.
After Rommel suggestion , I went ahead and check the many many lines of log and after hours came across and auth initialize issue with SSO.
how I fixed MY issue.
for some reason SSO service was up and running but it seemed like vituralcenter server tried to start first.
Once I restart the SSO service and waiting for it to come up, then I restarted the virtualcenter server service and it was successfully.
all nice and happy in this world now.
Thanks all for all your help and time
