我认为我得到了上述错误的原因.它是为了在客户端网络中工作而提供的公司代理(虚拟专用网络).没有这种连接，我经常会遇到相同的问题，无论是maven build还是npm install.

I think I got the reason for the above error. It is the corporate proxy(virtual private network) provided in order to work in the client network. Without that connection I frequently faced the same problem be it maven build or npm install.
