我有一个问题，就是无法登录GitHub。
之前一切正常，然后突然我的Flutter Build停止工作了。当我想要检出不同的分支以查看是否存在问题时，需要输入我的GitHub登录信息，这是奇怪的，因为Token还没有过期。无论如何，我生成了一个新的Token，并得到了以下错误：
无效的身份验证数据。无法分配所请求的地址: 连接
现在我怀疑一些JAVA安装的问题，所以安装了最新下载的JAVA版本。但并没有成功。
我怀疑JAVA的原因是构建时出现的错误也与JAVA有关。我只找到了一个讨论这个问题的线程，并且它建议在任务管理器中杀死所有与JAVA相关的应用程序，但我没有任何应用程序。重启计算机也没有帮助。即使在重新安装JAVA之后，此错误仍然存在。

真不敢相信，我刚刚关闭了NordVPN，一切都恢复正常了。有人知道Nord是怎么做到让所有JAVA东西停止工作的吗？还有为什么它突然崩溃了JAVA，我使用Nord很长时间了，之前从未发生过这种情况......
