I'm currently following a guide on how to setup Nginx on Ubuntu 20.04. I set up the Nginx configuration files and tested them succesfully.
$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
All went well until I had to restart Nginx.
$ sudo systemctl restart nginx
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
I tried both "systemctl status nginx.service" and "journalctl -xe" to find the issue.
systemctl
$ systemctl status nginx.service
ā nginx.service - A high performance web server and a reverse proxy server

Looking at the error logs I'm not sure what the issue is. Is it the "Not Found: /"? If so, what exactly is not found? I'm confused because shouldn't it be able to restart if the tests passed? At least that's what the guide said.
Any help would be greatly appreciated.
