Unable to connect to the BI Platform. Check your connection settings. (HDB 05408)


I have installed the SAP Lumira 1.31.1 in the distributed way you can find the link here.

Installing SAP Lumira 1.31 in Distributed Windows Environment

After doing so I had an issue connecting to the SAP BI Platform. The error message looks like this

I have already added the network mapping in the File preferences. The one piece that was missing was WACS server.

I did not see them in the node servers. They are located in the Core services and were stopped.

Enable and start these servers and once they are up you should be able to connect to SAP BI Platform.


Hope this helps someone!

      Hi MK - I'm getting the error you describe and this is the first page a google search brought me to.

      In your distributed environment, which node did you start the WACS?

      We are;  users --> balancer --> tomcat web --> firewall --> bi lum --> bi proc --> bi cms

      Also, I'm on Lum 2.1 with BOE 4.2 SP5, so maybe I don't even need to be running WACS anymore since that is not supported and Tomcat has taken over?
