If you look at the login form on the home page of that portal you will see

<form name="form_login" action="/portal/do_login.dwp" method="POST">

This means that the form should be submitted to

  https://www.orangeportal.sk/portal/do_login.dwp

Some forms submit to the same URL that contain them, but many don't.
This is one of the ones that requires submission to a different URL!
