apache2 突然无法提供 https

Question

Ubuntu 20.04.5 LTS（WSL2）上的 apache2 v.2.41 突然无法通过 https、浏览器或通过 进行连接wget。

它已经运行了几个月，我没有改变任何东西。

我尝试重新启动 Apache；但它仍然不起作用。

我的网站的.conf文件：

<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerAdmin <redacted>
    ServerName penguin.linux.test
    ServerAlias www.penguin.linux.test
    DocumentRoot /home/<redacted>/www
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

SSLEngine on
SSLCertificateFile /etc/ssl/certs/apache-selfsigned.crt
SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key
</VirtualHost>
</IfModule>

我跟着这些说明创建自签名证书，几个月前。我刚刚又运行了一遍：

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt

没有错误error.log。但是access.log显示一些当我使用浏览器访问时：

::1 - - [30/Jan/2023:08:34:02 -0600] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2.4.41 (Ubuntu) OpenSSL/1.1.1f (internal dummy connection)"

telnet [local IP] 443能够连接，这很奇怪。

浏览器似乎从未超时。Chrome Dev Tools 没有显示任何网络请求。
