replyGreat, Brother Pig, help me.
I have disabled the firewall.
The hosts file is as follows
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
127.0.0.1 localhost
172.20.2.60 localhost
Everything else is commented with #
replyThe server can connect normally, but the client cannot connect if it is replaced with a real IP. The client can connect using localhost. When accessed by other computers in the LAN, the connection still fails.

How is the local host configured? Another possibility is to check the firewall configuration
Let’s try restarting the computer, then there’s the configuration problem
