我目前正在尝试apache2在 Debian 延伸上创建一个页面来托管应用程序，但是当我a2ensite使用 HTTP 版本时它就不起作用，当我启用该版本时ssl，整个服务器都停止工作，即使是与此无关的页面一页。两个 conf 文件都很好，我被卡住了，知道可能出了什么问题吗？
编辑：日志显示这一点，在 09:06:37 我 a2ensite，并停止工作，在 09:07:01 我 a2dissite 并且它再次工作：

# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
