   Hello,
   I think I have related case so commenting this issue.
   My case is that I'm migrating from old 1.8.16 to 2.12.3 and in our old code we skipped hostname verification because it doesn't matter in our case but it create instead problems, so we have (snip from old impl):

           this.asyncHttpClient = new AsyncHttpClient(
               new AsyncHttpClientConfig.Builder()
   
                   .setSSLContext(sslContext)
   
                   .setHostnameVerifier(new HostnameVerifier() {
   
                       override verify(String hostname, SSLSession session) { log.debug("override hostname verification") ; true }
                   } )
   
                  .build()
   );
   

   How I can disable hostname verification in new version?

   Thank you

   and then:

   DefaultAsyncHttpClientConfig.Builder cfgBuilder = new DefaultAsyncHttpClientConfig.Builder();
   cfgBuilder.setSslEngineFactory(new SkipHostnameVerificationSslEngineFactory());

   to find out why above code will work.
