1. The problem I’m having:
I’m unable to convert a simple php config from NGNIX to Caddy for the NUT (Network UPS Tools) web site.
Although I can get the first page to work, the links that are .cgi don’t.
I’m pretty sure it’s just a config thing as the page can’t be found, but I don’t know how to fix it as I don’t know much about cgi or nginx.
I think the issue is that the main page is located in one location
/usr/share/nut/www
And the cgi scripts are located in another place?
/usr/lib/cgi-bin/nut
2. Error messages and/or full log output:

d. My complete Caddy config:
#NUT
:9877 {
root * /usr/share/nut/www/
php_fastcgi unix//var/run/fcgiwrap.socket {
root /usr/lib/cgi-bin/nut/*
}
file_server
}
5. Links to relevant resources:
This is what the NGINX config is
server {
listen 9876;
location = / {
return 301 /nut;
}
location /nut {
alias /usr/share/nut/www/;
try_files $uri $uri/ /index.html;
}
location /cgi-bin/ {
gzip off;
root /usr/lib;
include fastcgi_params;
fastcgi_pass unix:/var/run/fcgiwrap.socket;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
