Could you please:

Here are the attached files I could find:
- /etc/nginx/nginx.conf
- /etc/init.d/fcgiwrap
- /lib/systemd/system/fcgiwrap.service

Actually, all of these files are using the default config;  I have not made
any manual changes.
I only followed the docs here:
https://docs.yumaworks.com/en/latest/install/restconf.html#nginx-support
so I don't have any custom config.

Regarding spawn-fcgi, I cannot find its files. Not sure where there are.
I just installed it as the docs mentioned: sudo apt-get install nginx
fcgiwrap nginx-doc spawn-fcgi

Here is the output from systemctl and the package versions:

rostyslav at Rostyslav-i9-dev:~$ sudo apt-get install nginx fcgiwrap nginx-doc
spawn-fcgi
