Google measurement protocol doesn't register hit in GA. From browser works fine

Question

I don't see realtime pageview event when I try to send event from java.

Tried to build link with hit builder. - works fine.

Dropped url to browser - works fine.

Then I have tried to build the same from JAVA. While i'm using debug prefix for path google says all is ok "Found 1 hit in the request.".

public void purchaseEvent() {
        try (CloseableHttpClient client = HttpClientBuilder.create().build())

                    .setScheme("https")
                    .setHost("www.google-analytics.com")

            final URI uri = builder.build();
            final HttpPost request = new HttpPost(uri);
            final HttpResponse response = client.execute(request);
            String json = EntityUtils.toString(response.getEntity(), "UTF-8");
            LOG.info("response body - {}", json);
            LOG.info("Execute request to google analytics measurement protocol {}", response.getStatusLine().getStatusCode());
        }
        catch (URISyntaxException | IOException e)
        {
            LOG.warn("Not able to push purchase event to google analytics", e);
        }
    }

Required to specify user agent. This is optional field for measurement protocol.

This value works fine.
