TableauException: Operation timed out with Excel live connections

On Tableau Desktop, an Excel file containing 3 sheets stored in a shared folder were published separately as 3 live data sources: Table1, Table2, and Table3. After creating a workbook connecting to Table1, Table2, and Table3, published to Tableau Server and clicking "Refresh", the following error may occur:

Unexpected Server Error
TableauException: Operation timed out.


  • Tableau Server 10.1.6
  • Excel


The solution is to split the Excel file into 3 files (Table1.xlsx, Table2.xlsx, Table3.xlsx). Then republish all three data sources. 


Three live data sources were actually pointing to a single Excel file. That configuration caused file-locking.
