Debugging in VScode: "port already in use" error

[LoreZyra]

Problem

hexo server fails to bind to 127.0.0.1 while using node inspector. If you explicitly define the IP and port the same as that configured for Node Inspector, it will fail to start.

$(which hexo) clean && node --inspect-brk=4001 $(which hexo) server -i localhost -p 4001 --debug

However, if you don't define the IP and leave it to defaults, everything starts, but the browser doesn't reach the server over 127.0.0.1...

$(which hexo) clean && node --inspect-brk=4001 $(which hexo) server -p 4001

Expected behavior

Server should work Node inspector. How else does one troubleshoot issues if it won't bind on the same domain (IP) and port? IP alias?

The obvious workaround is to have inspector bind on 127.0.0.1 and Hexo server to bind to localhost.
