Hi all,
we are in a serious trouble with excel services and BI with SharePoint 2013.
We have a three tier Farm, 1 WFE, 1 App, 1 SQL with a fourth dedicated BI SQL with analysis (not in SharePoint mode). A Office Web Application server complete the infrastructure.
We are trying to make the powerpivot for SharePoint working. At the moment we have installed all the components using most of the various guide in the internet. We also created all the Kerberos SPN & delegation for all the components involved.
The same configuration was done in a test farm, identical to the produciont one, and it's working.
In production we are struck with the PowerPivot service application with the workbook activity chart with red X in it, and a error like "The data connection uses Windows Authentication and user credentials could not be delegated. The following connections
failed to refresh" if we try to refresh the data in the server health part above.
In the logs we have:
"We cannot locate a server to load the workbook Data Model" and, most specific:
ExcelService.PostProcessRequest: web method: EnsureWorkbookModel, got exception Id=NoStreamingServers; Microsoft.Office.Excel.Server.CalculationServer.SessionException: We cannot locate a server to load the workbook Data Model.
Digging more, we found this error:
There are no servers available or actively being initialized
According to :

I have communication issues between the servers, But I know that this kind of message could be generic.
I have tryed to telnet the Bi SQL server, opening the SQL MNGT from the SPS App server, I have no firewall active on the servers and they are virtuals on the same infrastructure. So I can't find out the problem. I suspect that is not a real network issue.
Please, anyone can suggest me how to understand where is the problem ? We are becoming crazy with this problem.
Thank you very much
