我正在尝试使用 https 配置旧的 OpenSuse 服务器。
http 虚拟主机似乎工作正常，但是当我尝试从浏览器加载 https url 时，我得到了：
This site can’t be reached
xxxxxxxx.it unexpectedly closed the connection.
Try:
Checking the connection
Checking the proxy and the firewall
Running Network Diagnostics
ERR_CONNECTION_CLOSED
我也尝试过测试配置（我不确定它是否真的可以……）：
openssl s_client -connect localhost:443

我尝试查看 apache 错误日志，每次尝试加载 https url 时都会出现此信息：
[Wed May 30 17:54:42 2018] [notice] child pid XXXXX exit signal Segmentation fault (11)
我已经安装了 gdb 并尝试调试 httpd 进程（我不确定输出的真正含义）：
