If you have implemented Basic Authentication on your WordPress site using .htaccess, Backuply may not function correctly due to restricted access. To resolve this, you need to whitelist your server’s IP address.
Steps to Whitelist Your Server IP:
Find Your Server IP

Edit the .htacess file
<RequireAny>
Require ip YOUR_SERVER_IP
Require valid-user
</RequireAny>
