Error when trying to enable Ingress within Gateway on K8s

We are able to access the gateway service when running the gateway service without ingress enabled. When we attempt to enable the ingress within the gateway service we are receiving the following error. Any thoughts or suggestions?

failed to create resource: Internal error occurred: failed calling webhook “”: failed to call webhook: Post “https://nginx-ingress-nginx-controller-admission.vault.svc:443/networking/v1/ingresses?timeout=10s”: service “nginx-ingress-nginx-controller-admission” not found
