Connection to a HTTP service fails

Question

Hi I am trying to connect to a service , but it fails with error below on calling

 CloseableHttpResponse response = httpclient.execute(httpget);
    data = IOUtils.toString(response.getEntity().getContent(),
                    StandardCharsets.UTF_8);

I am not calling close on response. Hence, I am assuming this could not be because the connection was closed before the entire data was read? How can I handle this in my code? How should this be handled in production ? Is this an issue with my code or the service?

It seems like the entity content can't be streamed because it is closed. Connection reset usually tells you that there's something wrong with your GET request/response.

However, you may also want to look into this:

What's the recommended way to get the HTTP response as a String when using Apache's HTTP Client?

The accepted answer shows a good way to handle HTTP responses (using EntityUtils and HttpResponse).
