Laravel + varnish port redirect

I have virtual machine with laravel 5 + nginx + varnish on board.

varnish works on port 80, nginx on 8080.

When i go to admin panel:

admin.mysite.ru

it must redirect to http://admin.mysite.ru/user/login/ if user is not log in. It correct. But when this happend, it redirected to admin.mysite.ru:8080/user/login/, that's wrong.

Redirect code is simple: redirect()->guest('/user/login/');

Thats problem come after i installed varnish, so, i cant understand how to resolve this problem. Could you give some advice or solution? Thank you!
