cannot monitor the client connection

[ArushArk]

Hello,how do I modify the code to specify the listening address? The network card IP of my VPS is the internal IP, not its public IP. The netstat command shows that the monitoring IP of CHAOS is the internal IP. I suspect that this is the reason why I cannot monitor the client connection.
The client shows a successful connection, and the server-side console can also see that the client has successfully established a connection, but the client's address is different from the actual client address, and the server-side web-ui interface does not show that the client has successfully connected.
