Hi,

I did an update of my server and after the reboot, cannot access the web gui.
I tried to restart the pveproxy service and the log shows “permission denied” and i did a chmod 777 /var/log/pveproxy/access.log command…
Also i tried to do apt install proxmox-ve

Nothing works...

Some ideas? I'm desperate

Thanks

What user did you run the command as? Could you post the output of:
  • pveversion -v
  • systemctl status pveproxy
  • systemctl status pvedaemon
Can the server still be accessed via SSH?

I would change this back to '640', as it shouldn't have anything to do with the issue.

Best regards,
Dylan

Could you also post the output of?

Okay, if it was an update from the GUI, it was likely a minor update anyway.

Ah, this explains it ;)
The directory /var/log/pveproxy and its contents should be owned by 'www-data'. Can you run the following command to see if it fixes the issue?
chown -R www-data:www-data /var/log/pveproxy

I had the same problem today with the exact same error.
The solution was the same for me.

Can anyone tell me how this can happen and why it happens?

The only thing I see right now is that Proxmox on this host is still on version 7.4-18 (I should really update this host)

For me the folder `/var/log/pveproxy` was non-existent and I don't understand how this could happen.

Anyway, thank you all!
I love this forum.
Thank you.
