Description

Hello, I have a question. While migrating from node14 to node20, I encountered the 'EADDRNOTAVAIL' error.

In fact, this problem can be solved by opening the host for the development server I want to use, and it verifies that the host is open and then runs it. Obviously, on node14, it was executed immediately without this process. Does anyone know what has changed in relation to what I said above as node versions go up?

The EADDRNOTAVAIL error in Node.js occurs when a program tries to bind a socket to an IP address or port that is not available or cannot be used.
