java.net.SocketException: Connection reset, using HttpURLConnection on page GET

Programmatically getting page with Java (HttpURLConnection) gives me error java.net.SocketException: Connection reset. Works with Python and with Postman.

Tried with other pages like gmail login page, ebanking login page etc. and it works, but only for one site (the one I need it to work) doesn't. Succeded with Python script, Postman also works, but Java doesn't

String url="https://********************/Login";
URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");
        con.setRequestProperty("Cache-Control", "no-cache");
        con.setRequestMethod("GET");

        int responseCode = con.getResponseCode();

Expected to not throw exception. Actual result is:

java.net.SocketException: Connection reset

...

Python script which works:

import urllib.request  as urllib2 
content = urllib2.urlopen('https://******************/Login').read()
print(content)

Try to HttpsURLConnection:

String url = "https://********************/Login";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

Code in sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:735)

enter image description here

maybe a proxy is reason of the problem.
