230 -When trying to restore a VM I noticed that it was very outdated. Before doing anything I got a `Permission denied (os error 13)` error message. I checked the permissions of the storage mount in proxmox cluster, generated new API key, removed and re-added the storage to node getting permission denied, and what gave it away I also got it when running the CLI command from proxmox-backup-server host.
