Google Reader API Authentication

Question

I am trying to authenticate on google api service using this snippet:

RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> converters =
   new ArrayList<HttpMessageConverter<?>> restTemplate.getMessageConverters());
converters.add(new PropertiesHttpMessageConverter());
restTemplate.setMessageConverters(converters);

Properties result = preparePostTo(AUTHENTICATION_URL)
                .using(restTemplate)
                .expecting(Properties.class)
                .withParam("accountType", "HOSTED_OR_GOOGLE")
                .withParam("Email", email)
                .withParam("Passwd", password)
                .withParam("service", "reader")
                .withParam("source", "google-like-filter")
                .execute();
String token = (String) result.get("Auth");

Now I have token like: DQAAAI...kz6Ol8Kb56_afnFc (more than 100 chars length) and try to get url:

URL url = new URL(LIKERS_URL + "?i=" + id);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.addRequestProperty("Authorization", "GoogleLogin Auth=" + token);
return url;

But while I am getting content using this url I get 401 Client Error exception. What can it be?

According to this question http://stackoverflow.com/questions/3100078/google-reader-authentication-problem all should be fine.

I can get the content simply pasting the url into browser.
