Kibana runs behind an Apache Webserver.

Hi @asp,

I'd check the health of the ES cluster when that request is running. You might need to optimize on the ES side to support the type of query you are doing. I'd wager a guess that if you ran the same query (that Kibana is running for the visualization) against ES directly, you'd see more specific errors.
