我认为我可以忽略Nextcloud的这些警告：
上次后台作业执行是在22小时前。好像有点不对劲。检查后台作业设置。

• 反向代理标头配置不正确，或者您正在从可信代理访问Nextcloud。如果没有，这是一个安全问题，可以允许攻击者欺骗他们的IP地址对Nextcloud可见。有关详细信息，请参阅文档。
• 您正在通过安全连接访问示例，但示例正在生成不安全的URL。这很可能意味着您处于反向代理的后面，并且覆盖配置变量没有正确设置。请阅读有关此插件的文档页面。

然而，我的桌面客户端应用程序不会让我连接时，网站的工作，它说：“投票网址不开始与HTTPS尽管登录网址开始与HTTPS。无法登录，因为这可能是一个安全问题。请与管理员联系”。无论我输入http://cloud.mydomain.com还是https://cloud.mydomain.com，都会发生这种情况。我正在使用Docker，并且在自己的Docker容器上有Nginx代理管理器和Nextcloud，但它们在同一个nginx2_default网络上。我在web gui中将其作为通过端口80传递容器名称，因为443由于某种原因不起作用，但只要我只告诉Nginx代理管理器HTTP，仍然以SSL连接结束，但仍然通过cert。
我已经在这个问题上停留了一段时间，我已经做了很多不同的帖子，但每次都是不同的情况，这是我得到的最接近的，但我仍然以0功能结束。一定要简单。
我觉得在这里做一个gist会更容易，这样所有的docker-compose文件都可以访问，还有nextcloud的.htaccess和config文件，我也把docker输出放在那里。
我将粘贴下面最相关的文件，但更容易。/home/james/newNextcloud/config/config.php
