Getting error partner ‘123.456.789.10:1234” not reached

Hi Experts,

We have installed SAP Business Objects Analysis, Edition for Microsoft Office (Version 1.4.7.3074) with required patch. But while trying to connect to SAP BW system after skipping SAP BO BI Logon screen, we are getting below error.

Also if we try to connect to BO server using SAP BO BI Logon screen, it displays error: “Error while checking availability of SAP Business Objects BI platform system”

Please note that we are facing this error only from a particular system. From other system, we can easily connect to BO server or BW server.  We are using Microsoft Office 2013.

Can you please let us know which settings do we need to change to stop this error?

Thanks in advance!!!
