Why doesn't the client connect to the server on the local network?

Question

C++ / C#

There is an online chat which is written in C#. Consists of two parts: server and client. The client is rummaged on 127.0.0.1:2222, the client is connected to this address. This works on one machine, but if you run it on the local network - on one PC the server and client, and on the other the client, then the client does not connect to the server. If I change the address from 127.0.0.1 to another one (the address of a server on the local network), I get a compile-time error that the address does not fit the context. Implementation - on sockets. Project - https://github.com/vyacheslavbevz/online_chat_bevz_

Answer 1

I found the solution here
I configured the addresses 192.168.1.1 and 192.168.1.2 on virtual machines, everything worked.
Plus, on virtual machines, you need to configure the network correctly (it started up normally from 8 times for me)
On both virtual machines, it should be identical
