在Ubuntu 18.04.3上安装后找不到Bookstack 404

Question

我按照官方指南安装了书架，其内容为：https://www.howtoforge.com/how-to-install-bookstack-on-ubuntu-1804/

安装正常，没有错误，但我无法访问应在www.mydomain.com/bookstack上提供的最终配置，它没有找到404。一直试图找出什么问题是徒劳的。

我的bookstack.conf如下：

<VirtualHost *:80>
 ServerAdmin bookstack@example.com
 DocumentRoot /var/www/html/Bookstack
 ServerName mydomain.com
 ServerAlias www.mydomain.com

<Directory /var/www/bookstack/>
    Options FollowSymlinks
    AllowOverride All
    Require all granted
 </Directory>

 ErrorLog ${APACHE_LOG_DIR}/error.log
 CustomLog ${APACHE_LOG_DIR}/access.log combined

# BookStack Configuration
Alias "/bookstack" "/var/www/bookstack/public"

<Directory "/var/www/bookstack/public">
  Options FollowSymlinks
  AllowOverride None
  Require all granted

  RewriteEngine On
  # Redirect Trailing Slashes If Not A Folder...
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)/$ /$1 [L,R=301]

  # Handle Front Controller...
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^ index.php [L]
</Directory>


<Directory "/var/www/bookstack">
  AllowOverride None
  Require all denied
</Directory>
# End BookStack Configuration

我确实更新了.env文件以反映子目录的更改。

这是一个SSL问题，如果是的话，我需要添加哪种配置？
