2596646 - Failed to connect to System in SAP Analytics Cloud (SAC)

You have implemented SAML SSO authentication in your SAP Analytics Cloud Live Data Connection to HANA using Direct Connection (CORS).

If you open an incognito tab in your browser, you can see your stories without problems and refresh your data. If you open a normal browser window, you get the error:

Failed to connect to System.

or

Unable to retrieve data from the datasource.
Error: Unable to get property “getlanguage” of undefined or null reference

If you clean your browser cookies, you can connect correctly.

If you capture network traffic using Chrome development tools, you can see that when connecting to your HANA server, instead of the usual HTTP response 200, you see a 303 See Other (redirection). It is going to be redirected to the SAML IdP as it considers that the session has expired:
