Hi, I am running dietpi on Rp4. Nginx installed as webserver. It simply stopped working. The error message i get when check on status is:

 nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; preset: enabled)
    Drop-In: /etc/systemd/system/nginx.service.d

Is there anything to fix it?
Thank you!

Did you change something on your system or did you make any update or so?
Because some files are missing and also your nginx config doesn’t seem right:

Nov 09 18:50:27 DietPi nginx[8807]: 2024/11/09 18:50:27 [emerg] 8807#8807: open() "/var/log/nginx/error.log" failed (2: No such file or directory)

Verify if the directory exists /var/log/nginx/

No i have not done anything, though i think the OMV that is installed along and functioned may have had autoupdate but i am not sure.
No that directory is missing.

Magic! Thanks it works!

Why can this happen, BTW?

/var/log/ is a tmpfs usually. It is possible that not all data was written back correctly during a reboot/poweroff. Such side effects typically only occur during unexpected shutdowns or crashes.
