Webclient not working Could not connect to one or more vCenter Server systems

Hi All,

I just installed vCenter 5.5 and appears to have finished fine.  I can log into the vSphere client on my computer and see my vcenter server. 

                              When I log into the webclient I cannot see my vcenter server.  there is nothing there.

                              I also get the following error message at the top of the webclient page when I log in:

                              Could not connect to one or more vCenter Server systems:
