DUPLICATE: Why don't custom login pages work on subdomains?

Bugs
1

Hello! Do you have any idea why custom login pages don’t work on subdomains?
Let me explain, on a main domain when accessing wp-login.php it shows the custom page configured in Bricks > Custom Authentication Pages, but doing the same on a WordPress installed on a subdomain doesn’t show the custom page but the default WordPress one.
Would you know how to fix this?
With an installation in the root directory, it works correctly. The issue arises when the installation is done in a subfolder.

I’ve tried it on 3 different servers, with different PHP versions, and the same thing happens on all of them (Siteground, Cdmon, and Hostinger).

WordPress installed in the root of the hosting

The same WordPress installation but in a subfolder of the hosting

Same here, exactly the same issue?
