我将 Ubuntu Server 从 22.10 升级到 23.04，它通过 Apache2 托管一些网站以及一些正常运行的 .NET 网站，但升级后，所有 Apache2 网站的请求都超时，其中 WordPress 网站显示 504 网关超时错误，.NET 网站确实加载，但过了一会儿也停止响应。重新启动 Apache2 对 Apache2 网站没有影响，但确实能让 Net 网站短暂地恢复工作。
我设置了一个新的空白 23.04 Ubuntu 实例（从 Ubuntu 网站下载 iso），安装了 Apache2、MariaDB 和 .NET 7，并将所有内容移过去，但在配置 Apache 之后，它的行为与旧服务器完全相同，所以它必须与配置方式有关，尽管这种情况已经一年多没有改变，只应用了更新。
旧服务器作为 VPS 托管在 DigitalOcean 上，而新服务器则通过 TalkTalk 业务连接托管在 Windows Server 上的 Hyper-V 上，该连接已经成功托管了 Postfix 邮件服务器。
我很感激任何关于这方面的想法。我尝试了一些步骤，例如禁用 http2 连接回到 http1.1，还禁用我添加的重写规则以将 http 流量定向到 https，但我所做的一切都没有任何变化，旧服务器已经运行良好一年多了。

因此，看起来请求在由 PHP 快速 CGI 模块处理时只是超时了
Error dispatching request to : (polling)
配置apache2的步骤如下：
已安装的软件包：
apache2, php, php-curl, php-mbstring, php-imagick, php-intl
启用 Apache2 模块：
suexec, authz_groupfile, headers, ssl, rewrite, proxy_http
启用 PHP 模块：
mbstring
PHP.ini 更改：
upload_max_filesize = 32M
post_max_size = 32M
date.timezone = Europe/London
最后我切换到了 HTTP2
sudo a2enmod http2
sudo apt install php-fpm
sudo a2dismod php8.1
sudo a2enconf php8.1-fpm
sudo a2enmod proxy_fcgi setenvif
sudo a2dismod php8.1
sudo a2dismod mpm_prefork
sudo a2enmod mpm_event
所以看起来
多于
似乎是 proxy_fcgi 模块导致了这个问题。我会尝试恢复到旧版本。
