Kubernetes客户端python API错误401-未经授权

我正在尝试创建一个Python客户端来连接并在AKS Cluster上的Pod中执行命令，但是当尝试连接时，我从客户端401 Unauthorized中收到消息错误。有人在API中遇到此问题吗？

API例外讯息：

kubernetes.client.rest.ApiException: (401)
Reason: Unauthorized
HTTP response headers: HTTPHeaderDict({'Audit-Id': 'ba23c2b3-d65b-4200-b802-161300119860', 'Cache-Control': 'no-cache, private', 'Content-Type': 'application/json', 'Date': 'Mon, 21 Sep 2020 18:21:59 GMT', 'Content-Length': '129'})
HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Unauthorized","reason":"Unauthorized","code":401}

我正在使用Python 3.8.2和Kubernetes 1.16.13
