为什么Nginx拒绝我与服务器的连接？

我正在尝试使用Kubernetes在alpine Linux上设置Nginx服务器。 我配置了.conf文件和负载平衡器（MetalLB）。 问题是，当我尝试连接loadBalancer提供的IP地址时，连接失败

以下是我尝试卷曲相同IP时出现的错误消息：

curl: (7) Failed to connect to 192.168.99.1 port 80: Connection refused

我不知道为什么这不起作用。 这是Nginx的.conf文件：

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        server_name _;

        root /var/www/localhost/htdocs;
        index index.html;
        return 301 https://$host$request_uri;
}
server {

        listen 443 ssl http2 default_server;
        listen [::]:443 ssl http2 default_server;
        server_name default_name;

        ssl_certificate /etc/nginx/certificate;
        ssl_certificate_key /etc/nginx/server.key;

        root /var/www/localhost/htdocs;
        index index.html index.htm index.nginx-debian.html index.php;

        autoindex on;
}

我的Nginx yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: container-nginx
  labels:
    app: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: image-nginx
        imagePullPolicy: Never
        ports:
        - containerPort: 80
        - containerPort: 443
---
apiVersion: v1
kind: Service
metadata:
  name: nginx
spec:
  type: LoadBalancer
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
      name: http
    - protocol: TCP
      port: 443
      name: https
      targetPort: 443

还有我的MetalLB的Yaml：

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - 192.168.99.1-192.168.99.20

有人知道出了什么问题吗
