There's a chance that you might be contacting to an external ip address in your application and you are not connected to the internet. So, Check your Internet Connection before making some change to host/dns or any other...
有可能您正在联系应用程序中的外部 IP 地址，而您没有连接到互联网。因此，在对主机/dns 或任何其他更改进行一些更改之前，请检查您的 Internet 连接...
There's also a possibility that you require a VPN Connection to be in the some particular network to access those external url/ip. So, check that too.
也有可能您需要某个特定网络中的 VPN 连接才能访问这些外部 url/ip。所以，也要检查一下。
