Desktop Refresh works but scheduled refresh has error

Hey v-zhangti ,

thank you for the information. 

I don't think that the table itself was the problem. The scheduled refresh worked fine when we started it manually and the scheduled the next day.

" The "semaphore timeout period has expired" message suggests that the server was waiting for a response from the data source, but did not receive it within a specified time period. This could be due to a variety of factors, such as network congestion or a slow data source."

To which network are you referring to? The source is Azure SQL. How could we drill down and investigate these issues further? The link you send doesn't cover these kind of errors.

Thanks again for the help
