Hi. Our company recently got new servers. Went from SharePoint 2013 to 2016.
We have SSAS tabular models that connect to SharePoint lists to retrieve data. We have used the standard URL:
https://"OurServerHere"/_vti_bin/ListData.svc
and it worked fine on 2013. But when modifying our models for the 2016 URL, we receive this error in Visual Studio 2015:
"Errors in the high-level relational engine. The following exception occurred while the managed IDbCommand interface was being used: The request was aborted: Could not create SSL/TLS secure channel..An error occurred while processing the partition......"
The odd thing is the connection TESTs OK and we can see data in the preview. But when trying to bring down the data/refresh the table, the error occurs.
Oh, another wrinkle... everything is working as expected in our Excel 2016 PowerPivot models with the SharePoint connections.
