yii2 always redirect to frontend/web - yii2-advanced-app

Question

When i want to access to backend yii2 always redirect me to frontend.
Example:
I have installed the yii2-user (dektrium) module in frontend and backend and yii2-admin (mdm) module only in backend . And when i want to acess to
http://localhost/american_eshop/yii-application/frontend/web/**user/admin/index**"
yii2 in the first place accessing to this route and after redirect me to "http://localhost/american_eshop/yii-application/frontend/web/".
I.E. i can get access to resourse but it always redirect me and i cannot undestand where i am in my site.
Sorry for my poor english...
