Cannot display web views from Project Pro

[m.edwards]

Hi-

Our users can connect to Project Server via ProjectProa
and PWA with no issues. We are, however, unable to display
the Project Center, Resource Center, etc, when attempting
to access these from the Collaborate menu from within
ProjectPro.

We get the intial screen (Project Center, for example),
and a message that Data is loading. Then, just before the
project list would be displayed, we get the following
error:

Project cannot access the Project Server
http://<server>/projectserver.

Please check the Project Server URL in the Collaborate tab
of the Options dialog box (Tools menu). Make sure the
server is functioning correctly, and is a valid Project
Server.

Retry accessing the Project Server -
http://<server>/projectserver

We CAN get to Portfolio Analyzer and Portfolio Modeler,
but not to the other Collaborate items. Any ideas?

thanks
