Cause

BAS Fiori application template tries to reach the following two URLs with a GET request and shows this error if 404 Unavailable is returned:

<URL from the destination>/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/ 

<URL from the destination>/sap/opu/odata4/iwfnd/config/default/iwfnd/catalog/0002/

 

Resolution

Make sure that valid XML is returned from either of the following two URLs:

<URL from the destination>/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/ 

<URL from the destination>/sap/opu/odata4/iwfnd/config/default/iwfnd/catalog/0002/

Use the username and password configured in the destination while testing the above URLs.

In case you are using SAP Cloud Connector, please use the internal host mapped to the destination URL instead of the URL from the destination and test this from inside the corporate network where SAP Cloud Connector is installed.

Also make sure that your connectivity to the backend is configured according to the following documentation:
