i did
$ systemctl status netbox.service
i got this result
Loaded: loaded (/etc/systemd/system/netbox.service; enabled; preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Thu 2024-09-19 06:37:00 UTC; 6s ago Docs: https://docs.netbox.dev/ Process: 117352 ExecStart=/opt/netbox/venv/bin/gunicorn --pid /var/tmp/netbox.pid --pythonpath /opt/netbox/netbox --config /opt/netbox/gunicorn.py netbox.wsgi (code=exited, status=1/FAILURE) Main PID: 117352 (code=exited, status=1/FAILURE) CPU: 2.467s
I am not a very experienced Linux user, so I don't know how serious the problem is.

Can you try to check what the logs say via journalctl -u netbox.service ?

You seem to have the netbox-proxmox-sync module either referenced but not installed or partially installed. You should either disable the plugin and remove references from configuration.py, or revise your setup.

Ok, thanks! I'll let you know if anything changes.

[Fullag1]

ok, it works again, I understood that this config.py does not play such a big role, but still I disabled the settings that I made earlier, went to "root" and re-enabled the service. Thanks you mate!
