Constant errors on new Vault node

I’ve added a new vault node to my existing cluster, as a part of replacing all the nodes with new, updated ones that have higher resources. It took a long time for the raft to replicate (about 45 minutes), and after that I have a few oddities.

  1. My logs on the new node are an endless stream of this:
    [DEBUG] core.cluster-listener: performing server cert lookup
    [DEBUG] core.cluster-listener: error handshaking cluster connection: error=“tls: no certificates configured”


  1. The new node shows up as a Voter: false in the output of raft list-peers

I’d like to resolve these issues before I start adding new nodes, but I’m unsure what to look at next.
