> Oh, and a Docker image like this one [1] would really help
https://github.com/layfe/docker_images
> Please provide two wire / context logs
I'v added the logs:
1) ok_sync_5_1.txt - success from HttpClient 5.1 (classic)
2) broken_async_5_1.txt - fail from HttpAsyncClient 5.1.
3) ok_async_without_body_5_1.txt - success from HttpAsyncClient 5.1. The only
change is an empty request body
> Could you please upgrade to the latest 5.1.x snapshot
I tried latest 5.1.x snapshot (with your commit), but the result is the same
(unexpectedly closed).
There are the logs (broken_async_snapshot.txt).
I noticed that the changed line is not called.

> Hello.
> We use AsyncHttpClient from Apache HttpClient5 (version 5.1).
> We faced an error when connection is unexpectedly closed using TLS, forced
> HTTP/1.1, and nginx version older 1.18.0.
> In the log below the server responds with 200 OK and an empty body.
> We can see response headers but connection is prematurely closed.

> That happens with the almost default configuration of the HTTP client (only
> versionPolicy and tlsStrategy are configured).
> To reproduce such behavior all of these conditions must be met:
> 1) Server must be accessed via nginx version older 1.18.0 (I tested 1.16.1
> and 1.18.0);
> 2) A request contains a body;
> 3) A response doesn't contain "Content-Length" header;
> 4) TLS is used.
> 5) HTTP/1.1 is used.
>
> I think there is a bug. We've tried httpclient5 (classic, version 5.1) and
> AsyncHttpClient (Netty based). Both of them work correctly.
