Then o Restrict access to wp-login.php

Hello, once again thank you for your attention.

I have installed or positioned in a subfolder eg: mydomain.com/business

Then o Restrict access to wp-login.php
Enable the option to redirect wp-login / wp-admin to the front-end login form.

It doesn’t work, is it caused by having it installed in a subfolder?

My domain looks like this: https://meusite.com.br/buscar/wp-admin/

and the same with an option Restrict access to wp-login.php or the client to obtain access or backend of the wordpress profile.

Tks
