Refresh does nothing after Preparing to refresh



We've been having a frequent issue lately (around 2-3 times per week), where we try to refresh the report manually from the Power BI Service and we get the typical message: "Preparing to refresh...":


Generally, after some seconds the dataset starts refreshing. Nevertheless, the issue that we've been facing is that it just doesn't start and does absolutely nothing. The gateway is online and works perfectly fine. Other reports refresh without any issues, but it's just that one that doesn't start. This situation usually fixes itself in around 30-90 minutes, but this report needs to be refreshed every 5-20 minutes depending on the data.


We don't know what it is and it's hard to pin-point the issue if we get no output whatsoever. We've tried changing the name to the report, restarting the gateway server, publishing the report again, but none has seemed to fix the issue. The only "solution" is waiting and it starts refreshing on itself (as it had delayed the refresh somehow) and it then refreshes 2 consecutive times on its own.


The report queries 4 tables, which in total it accounts for 670k rows, but less than 25 columns in total. It generally loads in 5-7 minutes.


Has anyone faced a similar issue and know of a possible solution?


Thanks in advance for any help.

Hi , @jchaconb ;

You could try to  reduce the size of the data source and then refresh to test whether it is related to the size of the data source. Secondly, you can refer to the following two articles.
