The reason for this problem is that there is no connection to the network (including LAN). This is a problem with the network communication protocol. It seems that the host name cannot be resolved without connecting to the network.

The reason for this problem is that there is no connection to the network (including LAN). This is a problem with the network communication protocol. It seems that the host name cannot be resolved without connecting to the network. So as long as you are connected to the network (or local area network), even if you cannot access the Internet, as long as you can ensure that the host name can be resolved to the IP address of the computer, there will be no error. But how to run under the completely offline model (without network cable) may require other settings?
