请教caddy代理php写法

最近在尝试驱动此php
https://www.hostloc.com/thread-758077-1-1.html

然后我想到了用caddy+php,简单小巧
但是我云探针 https ip:2096使用正常

https://域名:2096 {
root /usr/local/ServerStatus/web
tls /root/https/域名.crt /root/https/域名.key
timeouts none
gzip
}
https://域名:443 {
root /php/index.php
fastcgi / /run/php/php7.3-fpm.sock php
tls /root/https/域名.crt /root/https/域名.key
gzip
}

是不是我用这php写法不对啊?
