Problem bei der Installation ngnix

[e4e]

Hallo,

ich würde gerne den ngnix Server installieren und habe versucht es nach dieser Anleitung zu tun: https://pmg.proxmox.com/wiki/index.php/Quarantine_Web_Interface_Via_Nginx_Proxy

leider bekomme ich schon zu Beginn diese Fehlermeldung:

Woran kann das liegen?

Vielen Dank für Tipps

je nach config nehme ich an, dass der default vhost entfernt werden muss ....
(/etc/nginx/sites-enabled/default)
aber bitte die config vorher durchsehen und sicherstellen, dass sie vernünftig ist...
