HostSEO servers have WordPress bruteforce protection, so you may see a POPUP Authorization box to provide "admin" as your username and password, so the real wp-login.php will be shown.
However you can easily bypass that. Just add the following lines in the ".htaccess" under public_html folder.
<FilesMatch "wp-login.php">
AuthType None
require all granted
</FilesMatch>
This will do the job! No more pop-up authorization box for wp-login.php access!
