Couldn’t retrieve the data for this visual

Any luck with this? I have a report published to web that loads fine. If you the check a box in a selector list it sometimes shows data, sometimes shows the "Couldn't load the data for this visual" message.

Here is the thing: sometimes if I select a different checkbox and go back to my previous selection it works. Sometimes if I refresh the page it works, sometimes it fails for every checkbox I try.

Is there any word on what causes this?
