Client is fetching non-existing files

When using desktop clients, my Apache2’s error log gets full of that:

AH01630: client denied by server configuration: /var/www/html/dav
AH01630: client denied by server configuration: /var/www/html/cloud
AH01630: client denied by server configuration: /var/www/html/apps
AH01630: client denied by server configuration: /var/www/html/apps
AH01630: client denied by server configuration: /var/www/html/dav
AH01630: client denied by server configuration: /var/www/html/dav

That’s because I have the following conf:

<Directory /var/www/html>
  AllowOverride None
  Require all denied
</Directory>

Clients seem to work fine, but still: why are they doing it? is something misconfigured?

  • Nextcloud local path is /var/www/html/nextcloud and files are served through a subfolder
  • Desktop client version: 2.3.3
  • Nextcloud version: 12.0.4
