k8s拉取Harbor私有仓库镜像报错，提示 connection refused？

Question

harbor 环境：192.168.30.200，没有启用 https。

k8s 版本 1.24.5，容器运行时的版本如下

[root@master1 /etc/containerd]# ctr version
Client:
  Version:  v1.6.9
  Revision: 1c90a442489720eec95342e1789ee8a5e1b9536f

[root@master1 /etc/containerd]# nerdctl version

在 /etc/containerd/config.toml 配置了跳过证书校验的配置

[plugins."io.containerd.grpc.v1.cri".registry]
      config_path = ""

      [plugins."io.containerd.grpc.v1.cri".registry.auths]

      [plugins."io.containerd.grpc.v1.cri".registry.configs]
        [plugins."io.containerd.grpc.v1.cri".registry.configs."192.168.30.200".tls]
          insecure_skip_verify = true
        [plugins."io.containerd.grpc.v1.cri".registry.configs."192.168.30.200".auth]
          username = "admin"
          password = "Harbor12345"

使用 nerdctl 可以正常登录。

[root@master1 ~]# nerdctl --insecure-registry   login -u admin 192.168.30.200
Enter Password: INFO[0003] Error logging in to endpoint, trying next endpoint  error="Get \"https://192.168.30.200/v2/\": dial tcp 192.168.30.200:443: connect: connection refused"
Login Succeeded

但是拉取镜像失败，提示 connect: connection refused

不知道如何解决，有大佬能看一下吗？
