Kubernetes中配置LoadBalancer与Target Group后无法访问Nginx求助

我已经成功为Nginx配置NodePort并能正常访问，但配置LoadBalancer和Target Group后无法访问。刚接触Kubernetes，无法自行排查问题，相关信息如下：

nginx-service.yaml #

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  labels:
    app: nginx
    svc: test-nginx
spec:
  type: LoadBalancer
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 8080
      targetPort: 80
      nodePort: 30000
