I am using nginx as a reverse proxy. Below is the config file(/etc/nginx/conf.d/default.conf)

/fenrus/ here is the proxy.

I tried running "sudo service nginx start" because it hadn't started at boot, it gave out this error message.

"
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
"

So I ran the commands, this is the output of systemctl status nginx.service.

And this is the output for "journalctl -xe >> jornalctl.txt" passing the output into a text file to have it usable.

Since that one's output is so large so i uploaded it here https://paste.c-net.org/SyllableLocks

I'm no expert, but also try
sudo nginx -t
maybe it'll give more insight
