Thank you or answering. I deleted that ClusterRoleBinding, but still the same.
And I checked the log of vault pods, there are very few informations:
pod vault-0, vault-1, vault-2:
2023-04-04T02:12:08.788Z [WARN] core.raft: skipping new raft TLS config creation, keys are pending
2023-04-04T02:15:31.081Z [TRACE] activity: writing segment on timer expiration
pod vault-agent-injector-59b9c84fd8-lm5cj:
