External Data Refresh failed - Unable to refresh list data in Excel Web Access WebPart

Question

Hi,
I have created a PivotChart in Excel workbook that fetches data from a SharePoint list using "OData Data Feed". When refreshing the connection in Excel 2013, the updated data is displayed in PivotChart. But when i upload the same to a SharePoint
Library and refresh it through Excel Web Access WebPart, it throws an error.
After configuring PowerPivot for SharePoint, i am getting a "We cannot locate a server to load the Data Model" error.
Note -
SQL Analysis Service(PowerPivot) is in running state.
PowerPivot Server has been under Data Model in Excel Service setting.
The library location is added in trusted zone.
Using secure store didn't fix the issue.
Stack Exception
SSPM: Initialization failed on server : Microsoft.AnalysisServices.ConnectionException: A connection cannot be made. Ensure that the server is running. ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively

Hi,
For your issue, the possible reason is that the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis Services (PowerPivot) service is stopped.
Install PowerPivot for SharePoint or move the PowerPivot workbook to a SharePoint environment that has PowerPivot for SharePoint installed.
If the software is installed, verify that the SQL Server Analysis Services (PowerPivot) instance is running. Check Manage services on server in Central Administration. Also check the Services console application in Administrative Tools.
