An Apple Developer Login Issue: A 2016 Support ExperienceApple Developer 账号无法登录:通过 400 电话沟通解决

Translated from Chinese — .
A while ago I found that my Apple Developer account could no longer log in at https://developer.apple.com.
Whenever I tried to log in, it showed the screen below:

At first I thought it was a problem with the company network, but later I tried it at home, on a coworker’s computer, in Chrome and in Safari, and it still didn’t work.
I found someone online who had run into a similar problem and solved it by calling Apple support.
So I found the phone number,

I called 4006 701 855, Mandarin service, waited a couple or three minutes, and it was fixed.
In the end, they asked if I had any other questions. I said, “Can you tell me the reason?” The other side said, “We can’t tell you that.”
I asked, “Will using a VPN day-to-day cause any issues?” The other side said, “No effect.”
OK, problem solved.
前段时间发现自己的Apple Developer账号不能在 https://developer.apple.com 登录了。
只要登录就提示下图:

后来,开始以为公司网络问题,后来在家,在同事电脑,Chrome, Safari 都试了还不行。
网上找到有人遇到类似问题,打苹果客服解决了。
于是找到电话,

打了 4006 701 855 ,普通话服务,等了几个两三分钟,就解决了。
最后,问我还有什么问题,我说“能知道原因吗?”,对面说“不能告诉您”。
我问“平时使用VPN会有影响吗?”,对面说“没有影响”。
好吧,解决了。
