  • Failed to connect to system when using a reverse proxy to create live data connection to aremote HANA system in SAP Analytics Cloud
  • Google Chrome Developer Tools shows:

         403 Forbidden

         The server refused to fulfill the request


  • SAP Analytics Cloud

Reproducing the Issue

  1. Connect to SAP Analytics Cloud,
  2. Create a "Live Data Connection" > "SAP HANA"
  3. Choose "Path" as "Connection Type", and fill in the path of HANA system configured at httpd.conf file of Apache reverse proxy, and other required information
  4. Click OK 
  5. You get the error "Failed to connect to system" 


HANA restricts usage to particular origin hosts to make it more secure. The URL of the Apache reverse proxy server is not included in the list defined in the "allowOrigin" section under "cors" in the Application Access (.xsaccess) File of the target remote HANA system.


  1. Go to targeted remote HANA system's IDE Editor
  2. Log on
  3. Expand sap > bc > ina >service > v2
  4. Click .xsaccess 
  5. Locate "allowOrigin" section under "cors" and add the URL of Apache reverse proxy server.
  6. Save

 *Note: If you test the dispatcher rules for the remote HANA system by opening the following URL: https://<Apache Web Host>/<PATH>/sap/bc/ina/service/v2/GetServerInfo, it successfully returns the JSON response.
