Apache authz_core:error when accessing NC in subdir

Nextcloud version 15.0.2:
Operating system and version Ubuntu 18.04:
Apache or nginx version Apache 2.4.29:
PHP version 7.2:

Issue:
Since I first installed NC in a subfolder, everytime I access it (like domain.com/cloud) I get alot of errors in my apache2/error.log everytime the NC gets accessed:

[Fri Jan 18 15:21:51.598200 2019] [authz_core:error] [pid 3878:tid 547769057696] [client *.*.*.*:34944] AH01630: client denied by server configuration: /var/www/html/apps

My apache site conf for *:443 looks like this:

        Alias /cloud "/media/DATA/cloud/Nextcloud"

        <Directory /media/DATA/cloud/Nextcloud>
                Options +FollowSymLinks
                AllowOverride All
                Require all granted
                <IfModule mod_dav.c>
                        Dav off
                </IfModule>
                SetEnv HOME /media/DATA/cloud/Nextcloud
                SetEnv HTTP_HOME /media/DATA/cloud/Nextcloud
        </Directory>

Redirect to https is done with in the VirtualHost *:80

Redirect permanent / https://domain.com/

Access to /var/www/html is denied in the apache.conf itself so domain.com is not valid

So for some reason the browser (Firefox 64, haven’t tested others) is trying to access domain.com/apps etc. instead of domain.com/cloud/apps which get’s denied as those folders don’t exist.

Steps to replicate it:

  1. Setup NC in a folder that is not the webroot
  2. Configure apache with an alias as shown above
  3. Access NC and look at the log

Nextcloud log is empty

The output of config.php:

<?php
$CONFIG = array (
  'instanceid' => '*',
  'passwordsalt' => '*',
  'secret' => '*',
  'trusted_domains' =>
  array (
    0 => '*',
  ),
  'datadirectory' => '/media/DATA/data/Cloud',
  'dbtype' => 'mysql',
  'version' => '15.0.2.0',
  'dbname' => '*',
  'dbhost' => '*',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'nc',
  'dbpassword' => '*',
  'installed' => true,
  'memcache.local' => '\OC\Memcache\APCu',
  'overwrite.cli.url' => 'https://domain.com/cloud',
  'htaccess.RewriteBase' => '/cloud',
);

Thanks in advance
