Cannot upload file - debian - apache - GET "/seafhttp/protocol-version HTTP/1.1" 404

Seafile Server
1

Hi, I recently installed seafile CE following the official guide: HTTPS with Apache - Seafile Admin Manual

I used apache, certbot and everything is working, except that I cannot upload anything,

checking the logs in /var/log/apache2/seafile.access.log I found a 404 error:

"GET /seafhttp/protocol-version HTTP/1.1" 404 13508 "-" "Seafile/8.0.8 (Windows NT)"

And I cannot find any useful info in internet

this is apache configuration of
seafile.conf

  <VirtualHost *:80>
    ServerName seafile.millionairein10years.com
    DocumentRoot /var/www

    Alias /media  /opt/seafile/seafile-server-latest/seahub/media

    RewriteEngine On
