Vault Attributes Missing e.g. vault.version

vault.accessible
vault.cluster_id
vault.cluster_name
vault.version

Sometimes after a reboot my nomad clients don’t detect? their vault integration. I know this because my jobs won’t place due to vault.version not being a valid attribute on the node. If I restart the nomad service it normally fixes the problem.

I’m currently running 1.8.4, so haven’t tried 1.9.x yet and I only say sometimes. As the machines restart as part of their patch cycle.

Has anyone else seen this before?
