Hi, I implemented all recommended ste

Hi, I implemented all recommended steps in this article and sill - no luck to refresh the data ;-(. The data is coming from SSAS cube using Windows Authentication mode. Both the cube and Sharepoint are on different servers. The message says: Data Refresh Failed Unable to retrieve external data for the following connection... The data source may be unreachable, may not be responding, or may have denied you access. I spend days trying to get this done. Could you please help? Thank you.
