By using Query Monitor I found that Defender call two files and gettings errors.
First , "/wp-includes/theme-compat/embed.php" method is GET and Status is 404
Seconed, /wp-content/uploads/wp-defender/index.php , Method Head and Status is 403
Why Defender call them both ? And Why get errors ?
My Firewall company said that it is kind of dangrous to call both files
