Java http requests get banned on site

I am trying to receive and get info from site from my Java programm.

When I am using selenium - everything is ok, but when I try to use "prowser" or httpurlconnection - site blocks my IP.

I am setting user agent to Chrome/44.0.2403.155, and other parameters like in original site request (I take them with help of HTTPFox). I am handling cookies (cookies I get from FirefoxWebDriver), but always the same - my IP gets blocked
