I am running vault on Kubernetes with Postgres backend. Everything was working well, until an update triggered a pod restart. Vault started in sealed mode, and now I am not able to unseal. This is the message I see after entering the last unseal key:
Code: 500. Errors:
- failed to decrypt encrypted stored keys: cipher: message authentication failed`
Anyone has an idea why this is happening ? Am I not supposed not to restart Vault under no circumstance ?
