New CF10 Install coesn't see any updates

I just finished a new CF10 install (Standard Edition, 64 bit, Windows 2008R2).  Everything seems to work ok (Admin screens, etc).  Except that when I go to Server Updates > Updates to do the updates to the fresh install, and click on Check for Updates, it comes back and says "No updates were found."  I have 2 other CF10 systems, and each of them has no problem seeing that there is an update waiting.  Not seen this before - in the past a fresh install would immediately have the full list of Available Updates waiting to be installed.

Any ideas?

thanks
