我有一个正在运行的 nginx docker，多种的 site-config文件。
其中之一只是将所有 http 连接重定向到 https：
server {
listen 80;
server_name *.example.com example.com;
return 301 https://$host$request_uri;
}
所有其他site-config文件均用于我的其他 docker/服务，例如 Nextcloud 和 Plex。
每当我输入例如https://plex.example.com进入我选择的浏览器（甚至是 IE），它将显示具有 ssh 连接的正确网页。
但是，进入http://plex.example.com在这种情况下，只会返回一个空白页，并且不会将我重定向到 Plex。
有人有主意吗？
附言：
默认site-config文件是空的。但由于所有site-configs服务/docker 都在运行，我猜在额外的文件中进行重定向不会有问题。
备注： 以下是访问日志示例。错误日志为空（超过 3 个月没有新条目）。该日志来自通过 https 访问我的 plex 服务器。通过 http 访问任何内容都不会创建日志条目。

答案1
我找到了问题所在。首先，关于我的服务器/设置：它的监控 GUI 默认在端口 80 上运行，从未想过要更改这一点。我所做的只是将外部端口 80 映射到我服务器上的端口 84。84 是 let'sencrypt/nginx 正在监听的端口。
现在，我的路由器最近进行了软件更新，它选择在从我的 LAN 内访问 URL 时忽略端口映射。因此，我通过 http 请求访问服务器 GUI，并Access Denied在 curl 中收到错误。
在我对与我的服务器的连接进行 tracert 之后，我就有了这个想法。
我可能会将服务器 GUI 的端口更改为其他端口。但目前我很高兴，一切都运行良好
