Nginx real_ip module doesn't work in some conditions

[romkaltu]

Ok so it seams my mistake, everything is fine with this configuration, I
need extra step in backend to complete my task, as for specific example I
needed to set option in backend server (litespeed web server) option "Use
Client IP in Header" I must be accidentally disabled it.
