EKS fargate cluster with loadbalancer service - ERR_EMPTY_RESPONSE (port 80) + ERR_CONNECTION_CLOSED (port 443), logs on pod not showing requests

Question

i create a cluster:

eksctl create cluster \
--name example-cluster \
--region eu-central-1 \
--fargate \
--instance-types=t2.medium \
--full-ecr-access \

i update the kubeconfig:

aws eks update-kubeconfig --region eu-central-1 --name example-cluster

i use my kubernetes.yaml:

kubectl apply -f kubernetes.yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: openresty-deployment
spec:
  replicas: 1
  selector:
    matchLabels:

        ports:
        - containerPort: 80
        - containerPort: 443

      port: 443
      targetPort: 443
  type: LoadBalancer

pod and service are ok:

k get pods

logs on pod not showing any attempts to the container:

kubectl logs openresty-deployment-84d55495bb-qml2r
2024/03/07 08:04:36 [warn] 1#1: conflicting server name "localhost" on 0.0.0.0:80, ignored
nginx: [warn] conflicting server name "localhost" on 0.0.0.0:80, ignored

for port 443 i get ERR_CONNECTION_CLOSED

for port 80 i get ERR_EMPTY_RESPONSE

anyone has ideas?
