AWS EKS - NLB wird nicht installiert

We created a new EKS cluster, for this we installed a rancher with helm and installed the cert manager. We added the tags that are in the documentation in our subnets and security groups, as recommended. We followed the steps to create an NLB with the following documentation: https://docs.aws.amazon.com/de_de/eks/latest/userguide/aws-load-balancer-controller.htmlPolicy. With 'kubectl get deployment -n kube-system aws-load-balancer-controller' we get an answer that it is installed / ready. But in AWS under our load balancers there is no new one listed. Where can the problem lie here? Is there anything else we should consider?
