At my company, we have developed a number of PBI reports, the majority of which import their data from a series of Excel sheets on our network drives. All of the reports have been running on the same gateway setup and were working fine until last week when every one of them suddenly started sending me the error message below.
I can manually refresh a few of them in the Desktop app, where the refresh still works, for the time being but it's not ideal. Could there have been too many reports using the same gateway? And even now if I try to use the refresh button on PowerBI.com, it says it timed out after 3-5ish minutes.
