    Description

      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.
