Please use the following questions as a guideline to help me answer your issue/question without further inquiry. Thank you.

Which version of Elastic are you using?

[√ ] elastic.v7 (for Elasticsearch 7.x) [ ] elastic.v6 (for Elasticsearch 6.x) [ ] elastic.v5 (for Elasticsearch 5.x) [ ] elastic.v3 (for Elasticsearch 2.x) [ ] elastic.v2 (for Elasticsearch 1.x)

Please describe the expected behavior

Do not happen the exception : "caught exception while handling client http traffic, closing connection Netty4HttpChannel"

Please describe the actual behavior

Env: Win10(64bit), Win7(64bit) Elasticsearch-7.5.2, Elasticsearch-7.3.2 Action: use elastic.v7 do the bool(term) query. The exception happens: Elasticsearch-7.3.2 on Win10(64bit); Elasticsearch-7.5.2 on Win7(64bit) BTW: the exception does not happen at : Elasticsearch-7.5.2 on Win10(64bit)

Any steps to reproduce the behavior?

Only do the simple sentence : searchResult, err := client.Search().Index(indexName).Query(bq).From(fromIndex).Size(size).Pretty(true).Do(context.Background())
