Configuración de Apache2 que da 404 en la raíz del documento con http pero no https

Actualmente estoy tratando de hacer que mi servidor apache 2 funcione. Me puedo conectar con éxito a través de https. Pero http da un error 404.

vhost http

<VirtualHost example.com:80>
        ServerName example.com
        ServerAlias www.example.com
        ServerAdmin [email protected]

        DocumentRoot /var/www/example.com/html
        #<Directory /var/www/example.com/html>
        #        Options Indexes FollowSymLinks MultiViews
        #        AllowOverride None
        #        Order allow,deny
        #        allow from all
        #</Directory>

        <ifmodule mod_rewrite.c="">
              RewriteEngine On
              RewriteCond %{HTTPS} off
              RewriteRule (.*) https://%{HTTP_HOST}$1 [R=301,L]
        </ifmodule>

        #SSL Redirect
        Redirect permanent / https://example.com/

        ErrorLog /var/log/apache2/error.log
        LogLevel warn
        CustomLog /var/log/apache2/access.log combined
        ServerSignature On
</VirtualHost>

Y mi https vhost

<VirtualHost *:443>
    ServerName example.com
    ServerAlias www.example.com
    ServerAdmin [email protected]

    SSLEngine on
    SSLCertificateFile      /etc/letsencrypt/live/example.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem

    # Pfad zu den Webinhalten
    DocumentRoot /var/www/example.com/html
</VirtualHost>

Gracias por echar un vistazo.

Eliminé example.com:80 y lo reemplacé con *: 80.
