HTTP/1.1 500 Internal Server Error Get while webpage works Java

Question

I am tring to work with

HttpResponse httpResponse = httpClient.execute(method, context);

and getting this error

HttpResponseProxy{HTTP/1.1 500 Internal Server Error [Date: Mon, 23 Nov 2015 08:30:11 GMT, 
Server: Apache/2.2.20 (Ubuntu), X-Powered-By: PHP/5.3.6-13ubuntu3.8, Set-Cookie:

pre-check=0, Pragma: no-cache, Keep-Alive: timeout=5, max=100, 
Connection: Keep-Alive, Transfer-Encoding: chunked, Content-Type: application/json; charset=utf-8]}

The webpage appears as text a web browser and showing a valid Json text (all in one line) but aftet using (f12) i also get an error 500 .

I cant check the server error because its not mine.

I had search for previous error like mine and found : this and this and that one and many more

All of them are offering changing the header have tried changing the header - but it didn't solved my problem.

How do i know which header do i need ? What else could i try to fix it ?

This is not an actual answer since I cannot comment, but you can try open dev tool (f12 in Chrome) and open network tab, request to the url and see the request headers (since you said it works with browser request), and compare with the request you make from Java

Did you open Devtool and try request that webpage to see the request headers from network tab? – Dan Le Nov 25 '15 at 08:59
please check the added picture – 2Big2BeSmall Nov 25 '15 at 09:03
what does the browser show when you open dev tool? Also 500? – Dan Le Nov 25 '15 at 09:26
Yes it does - but the text inside the webpage is fine – 2Big2BeSmall Nov 25 '15 at 09:41

That's really strange. Can you post the full response here? You can click the request in network tab and see response and response headers – Dan Le Nov 25 '15 at 09:43

Could it be the authorization? It uses cookie/session state when you login and by using a httpclient request it doesn't have permission thus generate the exception? – Dan Le Nov 25 '15 at 12:26
