Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

• While following the guide for setting up AWS ALB for argogrpc service, the health checks fail for the argogrpc target group.
• This is happening as the AWS ALB is created with alb.ingress.kubernetes.io/backend-protocol-version set as HTTP2 to cater for HTTP traffic for argocd-server service whereas argogrpc service expects gRPC traffic.
• This is the reason why the health checks on the argocd-server target group pass whereas the health checks on argogrpc target group are failing.

To Reproduce

• Deploy argocd on EKS cluster in AWS
• Deploy AWS ALB Controller
• Follow instructions for deploying argogrpc service and ingress and check AWS ALB console for argogrpc target group
• Health checks for argogrpc target groups are failing

Expected behavior

• argogrpc target groups should not fail

Version

• Argocd helm chart version: 7.7.10

Which Argo CD image version are you using?

I was deploying ArgoCD via helm chart in my EKS cluster. I faced this issue during installation. ArgoCD helm chart version was 7.7.10 and ArgoCD version there is v2.13.2
