Url params not working -> access denied I'm new to Drupal 8.

I tried to do some batch process (for example installing modules or importing language files).

I got access denied for example on this address : 
http://localhost/en/batch?id=17&amp;op=start

I tried to investigate and debugging and find out in the file batch.inc

$request-&gt;get('id')


is Null

That means id=17 is not working. 

What am i missing? Is it related to my Nginx server block config?
It was related to my nginx config and fast cgi params

using apache instead of nginx temporarily fixed he issue
