When I try to use https://domain.co/login URL, it redirects to changed login URL

the plugin works fine for login.php or wp-admin folder, but when I try to check it using domain_com/login/ then it redirects directly to my changed login URL (Eg: domain_com/changed_url/). So I think this needs to work. If the plugin is unable to the login (domain_com/login/) url & it redirecting straight to the changed url then what is the use of it. Thats why I am giving only 1 star..
