Quick start

sudo nginx -t
sudo systemctl status nginx
sudo journalctl -u nginx -n 100 --no-pager
curl -I http://localhost

Recommended workflow

1. Install Nginx.
2. Test the backend application directly.
3. Add the reverse proxy configuration.
4. Run sudo nginx -t.
5. Reload Nginx only after the test succeeds.
6. Check logs and connectivity when an error occurs.
