Send Post over HTTPS - not working

Question

I am trying to send a POST request from my server to my another server. It is working well on http, when executed over https, it says internal server error - Unexpected end of file from the server. Here is my code for HTTPS POST.

URL url = new URL("https://.../Action")
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
System.out.println("Connection established");
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
conn.setDoOutput(true);
conn.getOutputStream().write(postDataBytes);

//Error in the following line
in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));

Your another server is configured properly for https ? are you able to hit it from browser using https. — Indra Uprade, Jul 20 '16 at 13:37
since it works with HTTP it should be correct i guess. I am actually sending the data as JSON. — Anand, Jul 20 '16 at 13:55

try setting it as application/json if you are sending json data. — Indra Uprade, Jul 20 '16 at 13:57
and one more thing you https call doesn't need any credentials to be authenticated ? i do not see that in your code though — Indra Uprade, Jul 20 '16 at 13:59
application/json don't work either. Regarding authentication, I am unsure that should we use any? The only difference I made in my HTTP request and HTTPS is the Http(s)URLConnection and the URL itself. — Anand, Jul 20 '16 at 14:08
Additionally, I also find that if I run 1st server(which will be triggered by browser) over HTTPS and the request (between the two servers ) over HTTP is not working either. — Anand, Jul 20 '16 at 14:10
You might want to install other server's cert into your server from where you are trying to invoke the url. — Indra Uprade, Jul 20 '16 at 14:26
You are right! I just got it working :) Thank you so much for helping me :) — Anand, Jul 20 '16 at 14:45

For HTTPS connection it is important to validate the SSL certificate of another server. For doing this, I used the solution posted by Shirish on the this link.

Thank you, @Indra Uprade for helping me to find the issue.
