HSM connection does not work on all management nodes

HSM connection works on some, but not all, management nodes.

Cause

The certificate and key pairs are missing for management nodes.

Resolving the problem

Check the HSM secret to confirm certificate and key pairs.

kubectl get secret hsm-secret -o yaml --namespace kube-system

Verify that key pairs for all management nodes are listed in the following format:

<IP>: <BASE64_ENCODED_CERTIFICATE>
<IP-key>: <BASE64_ENCODED_KEY>
