Error syncing 'serving-cert' secret and UI not accessible

Rancher Server Setup

  • Rancher version: 2.6.4
  • Installation option : Helm chart
    • EKS (v1.21)
  • Cert Details: ACM

Rancher pod is running but stuck with these logs and UI is not accessible. Can anyone help here?
I’m using external (ACM) for ssl termination, so have disabled the tls for the ingress.
