How to change the operating mode from HA to standalone?

Vault

Hi!
I did it like this:

standalone:
      enabled: "-"
      config: |-
        <some config>
ha:
      enabled: false

But I still get this:

/ $ vault status
Seal Type                awskms
Initialized              true
Sealed                   false
HA Enabled               true
HA Cluster               https://vault-0.vault-internal:8201
HA Mode                  standby
Active Node Address      http://10.8.121.212:8200

/ $ vault operator members
Get "http://10.8.121.212:8200/v1/sys/ha-status": dial tcp 10.8.121.212:8200: i/o timeout

Of course, this is not the ip-address of the node on which the pod (vault) is running.

I would like to find a way to go to one standalone(or HA with one replica) node and return it to a cluster of three without erasing the data and losing all the settings. Is this possible?

I’m not sure if it’s possible to change the way the storage is organized without initializing from scratch, but it seems possible to solve this problem by changing the number of replicas. So far, this hasn’t worked either:

Error
This is a standby Vault node but can’t communicate with the active node via request forwarding.

Is there a way to run elections in the cluster or explicitly designate a leader?
