We’ve been running Vault 1.11 for quite awhile on Kubernetes eks 1.22.15, we just recently started to receive this error message which we have not seen before, and believe its related to the load balancer certificate perhaps? Although the certificate is fine. Its self signed by the vault automated mechanism. We’ve looked high and low, but can not seem to find our specific error to zero in on in Vault. Hoping to see if anyone here may have run into this in their travels and working with Hashicorp Vault?
