RestHighLevelClient elastic listener timeout after waiting for [300000] ms

we're running a 3 node cluster of Elasticsearch, version 6.2.4

we launch an integration of new data by batch every morning.
we have listener timeout after waiting for [300000] ms every first request

restHighLevelClient.bulk(request);

we have this error after a moment of inactivity of the culster in this case All night inactivity

Is there a way to fix it?
