Hey there,

What software are you using for your web server? Nginx, Apache, HAProxy?

If you're using nginx, could it be possible that in one of your blocks you've bound the server-block to your IP address (instead of 0.0.0.0) and then you're redirecting to $host?

If you drop your server block below (for whatever web server you're using), we'll be able to help :)

This is my /var/apache2/sites-available/000-default.conf file.

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>
</VirtualHost>

This is my /var/apache2/sites-available/default-ssl.conf file.

<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
                ServerAdmin webmaster@localhost

                DocumentRoot /var/www/html
               <FilesMatch "\.(cgi|shtml|phtml|php)$">
                                SSLOptions +StdEnvVars
                </FilesMatch>
                <Directory /usr/lib/cgi-bin>
                                SSLOptions +StdEnvVars
                </Directory>
        </VirtualHost>
</IfModule>

Is it enough? or could you specify the path to get blacklist of my server?
