Java Https POST fails with connection timed out but works with Postman. Can anyone help me out?

URL url = new URL(“My url”);HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();Base64EncoderDecoder encoder = new Base64EncoderDecoder();String encoded = encoder.encodeToString(userName+”:”+password);conn.setRequestProperty(AUTHORIZATION, BASIC + encoded);conn.setRequestMethod(POST);conn.setRequestProperty(CONTENT_TYPE, FORM_URL_ENCODED);        conn.setConnectTimeout(10000);conn.setDoInput(true);conn.setDoOutput(true);conn.connect();

Can anyone tell me whats wrong with my code?
