Hi,

first, thanks for this work :) Recently we found that in certain environment (we are using filebeat in docker) using the latest beat with this plugin, sometimes we would receive 2021-07-26T05:36:40.104+0800 ERROR [http] [email protected]/http.go:227 Writing event to http failed with: Post "http:/xxx.com:12345/api/access": net/http: timeout awaiting response headers2021-07-26T05:36:40.104+0800 INFO [publisher] pipeline/retry.go:213 retryer: send wait signal to consumer 2021-07-26T05:36:40.104+0800 INFO [publisher] pipeline/retry.go:217 done

and the same compiled filebeat won't have such problems in most of our dockers. I wonder it may be some bugs in underly http client?

please help :)
