我在 nginx 中托管了一堆服务（通过子域），例如 mine.mydomain.com、doku.mydomain.com 等。多年来，它一直运行顺利（Ubuntu Server，现在已升级到 20.04 LTS，几乎所有服务，包括在 Docker 中运行的 nginx 本身）。但在设置新网络（新硬件、在 VLAN 中隔离内容）后，无法通过子域/域（mine.mydomain.com）访问儿童 minecraft 服务器，尽管我测试过的所有其他服务仍然运行良好。
我对端口 25565 (minecraft) 进行了端口转发，看看是否可以使用我的 externalIP:port 进行访问，绕过 nginx。这很好用。奇怪的是，现在我也可以访问 minecraft 服务器了虽然我的外部 mine.mydomain.com。我看不出这有什么关系，因为我为 nginx 转发了端口 80、443，这应该是需要的（这是我的旧设置）。但它是一致的，只要我删除端口转发，访问（通过 nginx，mine.mydomain.com）就消失了，我收到错误：
io.netty.channel.AbstractChannel$AnnotatedConnecttException: Connection refused:
我已经将很多 nginx 配置分开，但不同的文件如下。首先是特定于 minecraft 的文件，然后是用于比较的 dokuwiki 实例（运行良好），以及 ssl、nginx、代理配置。

（我有，other_domain.com因为我在两个不同的域上托管东西。但这other_domain.com只是一个网站，所有其他服务都在 mydomain.com 域上，每个服务都有子域，就像上面的两个例子一样）。
