There is EKS Cluster, AWS CNI plugin replaced by Calico(the cause of installing Calico here). After installing chart by helm I execute kubectl describe ingress -n my-ns and see an error:
...Failed deploy model due to Internal error occurred: failed calling webhook "mtargetgroupbinding.elbv2.k8s.aws"...
My ingress.yaml:
{{- if .Values.ingress.enabled -}}
{{- $fullName := include "front.fullname" . -}}
{{- $svcPort := .Values.service.port -}}
{{- if semverCompare ">=1.14-0" .Capabilities.KubeVersion.GitVersion -}}
apiVersion: networking.k8s.io/v1beta1

In the AWS console it seems everything ok, ALB has active status, but following the DNS name failed.
The interesting fact if I replace the Service type with LoadBalancer, Classic Load Balancer will be deployed and will work fine, DNS name works.
I realize that initial information could seem messy and insufficient, but I have no idea what direction to follow to solve the problem. I will be glad to provide all needed details whatever asked and will be appreciated for any help.
