I'm not sure if this is a valid question, but I kept running this error message when I try to refresh a Tableau report. It doesn't pops up every time, but enough to be very annoying. As far as I can see there's nothing wrong with the connection, because when this doesn't pop up the report works just fine.
I'm using version 10.3, and was instructed to use Extract instead of Live connection by our IT team. But the refresh has been really unstable and I can't figure out anything from a business developer's perspective.
Anyone has run into the same issue before? Is this a bug?
