Couldn't load the data for this visual.

The visual's query failed — commonly a timeout, a measure that errors under some filters, or a gateway/source issue.

Why it happens

• A query timeout on a heavy visual.
• A measure that only errors under certain filter combinations.
• The gateway is offline, or the source is temporarily unavailable.

How to fix it

1. Use 'See details' to read the underlying error — that message is the real diagnosis.
2. Test the suspect measure in a simple table visual across filter values.
3. Check the gateway status and credentials; reduce the visual's load; refresh.
