SQL Server timeout

[Anonymous]

When refreshing a dataset in the Power BI service i consistently encounter the folowing error after 20 minutes: 

"Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

This  timeout does not seem to be triggered on the sql server database, i expect this might relates to the command timeout settings in power bi desktop being blank.  I read that the defualt value here is 10 minutes, is this correct?  

And is there a way to see what portion of the refresh time is spend on  a particul source, knowing the dataset uses several sources.

Hi, @Anonymous 

If your connection lasts longer than 10 minutes(the default timeout), you can enter another value in Command timeout in minutes to keep the connection open longer.To find out which data source consume most refresh duration, you can use Performance Analyzer to help you check the duration of refresh. If the report is resided in Premium capacity, you can use Power BI Premium Capacity Metrics app to help you monitor key metrics.

Hi @Anonymous 

You can use the Command Timeout to ensure it runs for a longer period.
