Unable to open Planning CAC & Analyst

[rakkeshr18]

Installed IBM Cognos Planning 10.1.1 FP3 with IBM Cognos Business Intelligence 10.2.1 FP2 - All services seems to be up and running.
But when tired to open CAC or Analyst we are getting a window with "Navigation to the webpage was canceled".

When through the supporting document : http://www-01.ibm.com/support/docview.wss?uid=swg21613469
so far it doesnot help me with CAC.
Its totally weird as there are no error nor warning I could find, I would really appreciate if any one have any recommendation in this case.

Thank you.

Hey cogknown,

Go into Cognos Configuration on your CAC machine and copy out the Gateway URI value from the Environment section.  Paste this into the browser on your CAC machine and make sure you can get to the address.
