java でAPI呼ぶ時にjavax.net.ssl.SSLHandshakeException発生すること

だれか答えたらありがたいです

　　　　　　　URL url = new URL("https://xxxxRequest");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=utf-8 ");
//some headers and params
OutputStreamWriter os = new OutputStreamWriter(conn.getOutputStream());
os.write(json.toString());
os.flush();
conn.connect();
recode = conn.getResponseCode();
