Error while conecting Cognos Planning Contributor through IE or Mozilla


When I login to Planning contributor web client and click on a particular planning model through Internet Explorer 9(32 bit) and Mozilla firefox I am getting the below error.
I am running CognosRCP.msi file but even after that I am getting the same error.

This is happening when I access the planning application from other computers on the same network.But when I access the planning model directly on planning server then I am able to open the same without any error.
