看不出是哪里的问题，是我的K8S哪里不对了吗？

无人关注啊。

实际上这个10.233.90.155 POD 上根本不存在9443端口，莫名其妙啊，只有8443端口，如果配置成8443，会报证书不匹配。
这到底该如何处理呢？

你的notification manager operator的版本不对，你把镜像换成kubesphere/notification-manager-operator:v1.4.0试试

    添加秘钥后，可以了，多谢大佬指点！！！
    就是有些疑惑，为啥莫名其妙的就这样子了呢，是KUBESPHERE会自己悄悄升级吗，还是会自己变动的？从而导致哪里对不上号了？我没有动过里面的东西啊。

      大佬帮我也看看把，我也是这个问题，不过我按照的是最新的版本kubesphere3.4.1的，突然就出现了登陆不上，我看是因为ks-apiserver启动不了，调用notification-manager-webhook（kubesphere/notification-manager-operator:v2.3.0）总是报证书问题。
