Query Data Error

I’m having a problem with my dashboard auto-updating. Sometimes it returns the data normally, but most of the time it gives the error: “Query data error”. I’ve searched and tried to change the query but this error persists and doesn’t give me more information than it might be.

Does anyone have an idea what it could be?

I decided. The problem was that I repeated the query for each visual instead of using the query on a single visual and using this data for the other visuals through the “dashboard” option.
