您正在使用的 DNS 服务器 (192.168.1.21) 似乎配置不正确。
尝试

你应该得到这样的东西：

其中重要的部分是 ANSWER 部分中的两行。第一个是提供规范主机名的 CNAME (api-sandbox.amazon.co.jp)，第二个是该主机的 IP 地址。
然后与管理 DNS 服务器（在您组织内的本地服务器）的人交谈，找出问题所在。
我们正在本地环境中测试 Amazon Payment Java SDK 应用程序。启动应用程序时，会显示 Login with Amazon sandbox 按钮。单击该按钮，我们输入亚马逊帐户用户名和密码，之后出现异常。我对 Amazon Payment 的运作方式一窍不通。非常感谢任何帮助！

您正在使用的 DNS 服务器 (192.168.1.21) 似乎配置不正确。
尝试
dig @8.8.8.8 api.sandbox.amazon.co.jp
你应该得到这样的东西：
$ dig @8.8.8.8 api.sandbox.amazon.co.jp
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.4 <<>> @8.8.8.8 api.sandbox.amazon.co.jp

其中重要的部分是 ANSWER 部分中的两行。第一个是提供规范主机名的 CNAME (api-sandbox.amazon.co.jp)，第二个是该主机的 IP 地址。
然后与管理 DNS 服务器（在您组织内的本地服务器）的人交谈，找出问题所在。
