Courier Fetch Timeout

Time out error happen in kibana

Courier Fetch: All or part of your request has timed out. The data shown may be incomplete.

chrome developer console show no special error request.

But when I run same query(copied from kibana request json) directly to elasticsearch on cerebro It successfully queried the full result without timeout.

I repeated same query kibana then rest call several times.
Kibana always timedout, http call always succeeded.
(I set the kibana time to absolute time range)

no special logs found in elasticsearch server and kibana server.

kibana's elasticsearch timeout is 30s.
What's the problem with kibana?

version of kibana is 5.2.2

Is the JSON sniped from running the request in cerebro? Notice that it also includes the "timed_out": true flag from elasticsearch.
