我一直在尝试将我的Nextcloud更改为反向代理。以前没有反向代理也能正常工作。但是我想将它移到这个反向代理后面（使用通配符证书）。所以今天我重新安装了一次，但是还是没有成功。也许有人能帮助我。
Ubuntu：20.01 LTS Nexcloud安装与快照（Nextcloud 20）
已执行的命令：

$ sudo snap install nextcloud
$ sudo nextcloud.manual-install admin ###password###
$ sudo snap set nextcloud ports.http=81
$ sudo nextcloud.occ config:system:set trusted_domains 0 --value=https://cloud.mydomain.com
$ sudo snap connect nextcloud:removable-media
$ sudo nano /var/snap/nextcloud/current/nextcloud/config/config.php

• 〉我将数据目录更改为我使用的目录
  $ sudo nano /etc/apache 2/sites-available/000-default.conf -〉这里我粘贴了你的代码片段。这里我显示了我完整的000-default.conf（因为我认为问题可能在这里）。Ps：我还运行了一个jellyfin服务@ jellyfin.mydomain.nl（这是工作的）。在我的主机服务器上，我做了两个CNAME条目：1=cloud@mydomain.nl2=jellyfin@mydomain.nl

======================
如果我输入https://cloud.mydomain.nl，它会将我重定向到标准的apache，它的工作网站运行在80端口。
我真的很希望你能帮助我，因为这让我发疯！非常感谢！
