我有一台装有 Apache2.4 的 Ubuntu 服务器。（Ubuntu 20.04.2 LTS（GNU/Linux 5.4.0-74-generic x86_64））
我将 Apache 从 2.4.46 更新到 2.4.48，除通过 HTTPS 下载 .bin 文件外，我测试的其他一切都正常运行。我的设备开始下载文件，但甚至无法下载文件的第一个数据包，并且显示“对等端已关闭连接”。
下载 .bin 文件之前曾与 Apache 2.4.46 一起使用。
apache2ctl -S

我尝试了很多方法来解决这个问题，但都没有奏效。我想知道这些 Apache 版本之间发生了什么变化，可能导致了这个问题。我希望有人能帮我解决这个问题，或者知道我应该尝试什么。
