javax.net.ssl.SSLPeerUnverifiedException: No peer certificate on HttpClient but works fine with HttpUrlConnection

Question

Previously,I used HttpClient for a http post request and it was working fine, until I believe the server team made some changes. Then I kept getting javax.net.ssl.SSLPeerUnverifiedException: No peer certificate Exception.

Then, after alot of scratching my head, I tried HttpUrlConnection and it works fine, but still I can't figure out why I got that exception while using HttpClient.

Before code was :

public String postDataAndGetStringResponse( List<NameValuePair> nameValuePairs ) {
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost( link );

        try {

            post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse response = client.execute(post);

            InputStream is = response.getEntity().getContent();

            String result = "";

            if (is != null) {
                BufferedReader reader = new BufferedReader(
                        new InputStreamReader(is));

                String l = "";
                while ((l = reader.readLine()) != null) {
                    result += l;
                }

                reader.close();
            }

            is.close();

            return result;
        } catch (Exception e) {
            Logger.printStackTrace(e);
            return ServerUnrechable;
        }


    }

I did check the server using https://www.sslshopper.com and everything is ticked, it would be very helpful if anybody could tell me the cause to this issue.

One of the most likely causes is that the server you're trying to use now relies on Server Name Indication.

SNI support was added a to HttpsURLConnection in Android, but not to the Apache HTTP Client bundled (now deprecated/removed). See this related question for details.
