i’m deploying 2.7.5 rancher on EKS 1.25 or 1.26, i need to use my own certificate from ACM

deploying with the values below :

ingress:
  enabled: true
  extraAnnotations:
    alb.ingress.kubernetes.io/certificate-arn: "<ACM-ARN>"
    alb.ingress.kubernetes.io/scheme: "internet-facing"
    alb.ingress.kubernetes.io/success-codes: '200,404,301,302'
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS": 443}]'
    alb.ingress.kubernetes.io/target-type: 'ip'
 
  ingressClassName: alb

tls: external

hostname: "rancher.example.com"
bootstrapPassword: "admin"

i’m getting 404 (even in https://rancher.example.com/dashboard/?setup=admin aswell), in the pod logs :

I am having the same problem. I used EKS 1.24 k8s cluster with my own certificate from ACM and upgraded rancher from 2.7.4 to 2.7.5. everthing seems really fine but the dashboard doesn’t work. I researched on the internet couldn’t find a solution.
