BusinessObjects connection is not working

Context

Connection to the BO instance is failing with message:

Could not reach CMS 'hostname:6400'. Specify the correct host and port and check for network issues. (FWM 20030)

Problem

See SAP note: [https://launchpad.support.sap.com/#/notes/2151044]

How to fix

To resolve this issue the local system must be able to resolve the hostname of the remote CMS, which is being returned by the name server (6400).

This can be achieved by:

Either adding the hostname and IP address to DNS

OR By adding the information to the hosts file of the local operating system:

Go to C:\Windows\System32\drivers\etc (/etc/hosts on linux / unix)

Edit the “hosts” file

Add a new row to the end with the IP address, the server name, and the fully qualified domain name like: 10.100.100.100 servername servername.FQ.DN
