Previously, the Proxmox VE Node Info service could fail when the Proxmox VE API did not include a subscription status in its response — for example on nodes where subscription data is absent or incomplete.

The service now handles a missing subscription status gracefully:

  • If no subscription status is available and no required subscription status is configured, the service reports OK with "Subscription: n/a".
  • If a required subscription status is configured but no status data is present, the service reports WARN with "Subscription: n/a".
