title: OKHttp Caused by: java.io.EOFException: \n not found: limit=0 content=…
body: <p>I have encountered this problems in occasionally case, my website do NOT have this issue before today, when I encounter this issue, I try to resolve it by check my code and track issue log, even try <strong>stack-overflow</strong>, the anwser may the list:</p>
  
  <ol>
  <li>set retryOnConnectionFailure(true) when you create a OkHttpClient
  instance.</li>
  <li>set header("Connection","close")</li>
  <li>set header("Accept-Encoding", "identity")</li>
  </ol>
  
  <p>But none of these could fix my issue, I also try to use addNetworkInterceptor to instead of addInterceptor, it does NOT work though.</p>
  
  <p>Finally, I try to go back my previos version. Well, my previous code as follow:</p>
  
  <pre><code>response.setStatusCode(HttpStatus.UNAUTHORIZED);
  return Mono.empty();
  </code></pre>
  
  <p>and now:</p>
  
  <pre><code>response.setStatusCode(HttpStatus.UNAUTHORIZED);
  return response.writeAndFlushWith(Flux.just(Flux.fromStream(
                      Stream.generate(() -&gt; ASRUtil.buildNLUResponse(ResponseEnum.TOKEN_NOT_EXIST))
                              .limit(1)
                              .map(ASRUtil::convertNLU2DataBuffer)
  )));
  </code></pre>
  
  <p>I use the above code just want to reminder customers of their tokens invalid or NOT exists.
  But, it seems to cause the issue.</p>
  
  <p>Any suggesion is welcome.</p>
  
  <p>log attachment:</p>
