why java post method connection timeout even it runs on browser?

I look network on developer tab(google chrome) and here is the ss
I want to get data on java app.
My code is here:
String urlParameters = "tabloNo=4&yil=2017&ay=2&paraBirimi=TL&taraf=10001";
byte[] postData = urlParameters.getBytes( StandardCharsets.UTF_8 );
int postDataLength = postData.length;
String request = "http://172.168.12*.15/getreport";
URL url = new URL( request );
HttpURLConnection conn= (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setInstanceFollowRedirects(false);
conn.setConnectTimeout(10000);
conn.setRequestMethod("POST");
conn.setRequestProperty("Accept", "pplication/json, text/javascript, */*; q=0.01");
// conn.setRequestProperty("Accept-Encoding:", "gzip, deflate" );
conn.setRequestProperty("Accept-Language", "tr,en;q=0.8" );
conn.setRequestProperty("Content-Length", Integer.toString(postDataLength ));
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
conn.setRequestProperty("Host", "ebulten.bddk.org.tr" );
conn.setRequestProperty("Origin","http://172.168.12*.15/");
conn.setRequestProperty("Proxy-Connection", "keep-alive" );
conn.setRequestProperty("Referer", "http://172.168.12*.15/" );
conn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36" );
conn.setRequestProperty("X-Requested-With","XMLHttpRequest" );
conn.setUseCaches(true);
try(DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) {
wr.write( postData );
}
it gives Connection timed out: connect
note:
it is public website and everyone read data. I want to read it with programmatically.
thanks in advance

HttpURLConnection with https InputStream Garbled

I use HttpURLConnection to crawler https://translate.google.com/.
InetSocketAddress addr = new InetSocketAddress("127.0.0.1", 1082);
Proxy proxy = new Proxy(Proxy.Type.HTTP, addr);
url = new URL("https://translate.google.com/");
HttpURLConnection conn = (HttpURLConnection) url.openConnection(proxy);
conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");
conn.setRequestProperty("Connection", "keep-alive");
conn.setRequestProperty("User-Agent",
"Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36");
conn.setRequestProperty("Accept", "*/*");
Map<String, List<String>> reqHeaders = conn.getHeaderFields();
List<String> reqTypes = reqHeaders.get("Content-Type");
for (String ss : reqTypes) {
System.out.println(ss);
}
InputStream in = conn.getInputStream();
String s = IOUtils.toString(in, "UTF-8");
System.out.println(s.substring(0, 100));
Map<String, List<String>> resHeader = conn.getHeaderFields();
List<String> resTypes = resHeader.get("Content-Type");
for (String ss : resTypes) {
System.out.println(ss);
}
Console is
But When I change url to http://translate.google.com/.
It works well.
I know actually HttpURLConnection is HttpsURLConnection when i crawler https://translate.google.com/.
I try to use HttpsURLConnection and it still garbled.
Any suggestions?

conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");
The response is compressed, because the above line tells the server that the client is able to understand encodings specified in Accept-Encoding.
Try to comment this line or handle this situation.
There's a more specific implementation for HTTPS i.e. HttpsURLConnection, in case you're interested in https-specific features, e.g.:
import javax.net.ssl.HttpsURLConnection;
....
URL url = new URL("https://www.google.com/");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

I accept Jerry Chin's answer.Solves my problem.
My answer just recording how i resolve this problem.
If this approach is unreasonable.Let me know, I'll remove this answer.
conn.setRequestProperty("Accept-Encoding", "gzip, deflate, sdch");
And then I check response Content-Encoding.It's gzip.
So i use GZIPInputStream to receive.
InputStream in = conn.getInputStream();
GZIPInputStream gzis=new GZIPInputStream(in);
InputStreamReader reader = new InputStreamReader(gzis);
BufferedReader br = new BufferedReader(reader);
The InputStream is normal.
BTW,If you don't need Accept-Encoding,you can remove it.
And do not forget check user-agent. It's very important and different operating systems corresponding to different user-agent.

How to decrypt HttpsURLConnection

My code makes POST request to a website, but the response looks like encrypted, with weird characters. When i configure my app to use fiddler proxy, the response is valid. How can i make my app decrypt this response?
public class Login {
public Login() throws Exception {
URL url = new URL("https://account.leagueoflegends.com/auth");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setDoInput(true);
conn.addRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36");
conn.addRequestProperty("Cookie", "xxx");
conn.addRequestProperty("Content-Length", "406");
conn.addRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
conn.addRequestProperty("Accept-Encoding", "gzip,deflate");
conn.addRequestProperty("Connection", "keep-alive");
conn.addRequestProperty("Referer", "xxx");
conn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write("xxx");
writer.flush();
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
writer.close();
reader.close();
}

You are explicitly requesting a zipped stream:
conn.addRequestProperty("Accept-Encoding", "gzip,deflate");
Remove that line to remove the compression. Compression is different from encryption fortunately, it doesn't require you to supply a key.

}
The code is very messed up because i tryed manytime to fix my connection problem.
Please help with a better Solution.

Hm, I will show my working code with JSON, but maybe you can modify it.
URL url = new URL("http://xcxcxcxcxcx");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(jsonObject.toString().getBytes().length));
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.connect();
DataOutputStream out = new DataOutputStream(connection.getOutputStream());
out.writeBytes(jsonObject.toString());
out.flush();
out.close();
InputStream is = connection.getInputStream();
InputStreamReader reader = new InputStreamReader(is);
BufferedReader r = new BufferedReader(reader);
StringBuilder total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
JSONObject jsonObjectResult = null;
if(typeOfMethod == 0){
JSONTokener tokenizer = new JSONTokener(total.toString());
jsonObjectResult = new JSONObject(tokenizer);
}
connection.disconnect();
return jsonObjectResult;
There is some differences between getting result from InputStream.

Java - Read cookie after a post

I'm having trouble reading what cookies are being sent when making a POST in java.
Here's my code:
public static void main(String[] args) throws MalformedURLException, IOException {
String urlParameters = "votebut=";
String request = "http://www.runelocus.com/toplist/vote-17648.html";
URL url = new URL(request);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0");
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length));
connection.setUseCaches(false);
DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
List<String> cookies = connection.getHeaderFields().get("Set-Cookie");
for (String cookie : cookies) {
System.out.println("Cookies: " + cookie);
}
connection.disconnect();
}
This is what it prints:
Cookies: PHPSESSID=48863f8c3adcbddf0e77e7f1b450fc0e; path=/
This is what I want it to print:
ki_u=68debd85-c1af-f1ff-2e6c-4146755c6e26; ki_t=1354418220596%3B1354418220596%3B1354422379616%3B1%3B36;
Any help please?
Thanks

It is not possible to read that cookies in that way.
In response to http://www.rune...17648.html you only get PHPSESSID cookie in response headers.
That cookies which you are looking for (ki_u and ki_t) are set by JavaScript code in this file:
http://s3.amazonaws.com/ki.js/45645/919.js
So to actually get that cookies values you need to replicate browser behavior or actually use a browser (to request the html page, parse it, download referred resources (particularly 919.js) and execute JavaScript code).
