apple itunes connection troubles

首先，使用报告中的 CLI、iOS Runtime 和 XCode 版本，通过 tns apple-login 和 tns appstore 重现失败。查看 issue 中链接的诊断报告指南，并将身份验证响应与在 Apple developer website 上正常工作的登录进行比较。当两个命令都能成功进行身份验证并上传到 TestFlight 时，即表示完成。

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.2.0
• Cross-platform modules: 7.1.4
• iOS Runtime: 7.1.1
• XCode Version: 12.4

Unfortunately all commands tns apple-login and tns appstore fail with

The server returned unexpected response: Unauthenticated
