I recently installed a fresh instance of Report Portal, but cannot get a successful connection to my OLAP cube. Under Admin Settings -> Connections it always gives the error message "The underlying connection was closed. An unexpected error occurred on a receive." when I try to test the XMLA connection.
2. To test the connectivity, create a text file and rename it to Test.udl. Double click to open it. Under the provider tab select "Microsoft OLEDB Provider for Analysis Services". Under the connection tab > Data Source enter your server name, selected initial catalog and click Test.
