hello all my setup is as such: > nginx(\*:443) -\> kibana(127.0.0.1:5601) -\> elasticsearch (127.0.0.1:5106) using kibana with elasticsearch for anything under 3 days timestamp is perfect and it runs smoothly; though if i seek back longer it gives me a gateway timeout... in nginx error log i see "upstream prematurely closed connection while reading response header from upstream" > 1852#0: \*200 upstream prematurely closed connection while reading response header from upstream, client: X.X.X.X, server: kibana.interface.fake, request: "POST /elasticsearch/\_msearch?timeout=0&ignore\_unavailable=true&preference=1437744706387 HTTP/1.1", upstream: "[http://127.0.0.1:5601/elasticsearch/\_msearch?timeout=0&ignore\_unavailable=true&preference=1437744706387](http://127.0.0.1:5601/elasticsearch/_msearch?timeout=0&ignore_unavailable=true&preference=1437744706387)", host: "kibana.interface.fake", referrer: "[https://kibana.interface.fake/](https://kibana.interface.fake/)" i don't have a problem in waiting for any time it takes to show me the output so i increased every proxy\_read and proxy\_send as well as header timeout i know of in nginx; and that is still causing a gateway timeout when query takes longer to execute... server has good specs though internet bandwidth on client side is a bit slow so it may take a while to retrieve all data and visualize them... any advice on how to fix this ? ---

Maybe try increasing the timeout on nginx's side. ---
