I'm trying to use the debugger through chrome and it keeps giving me this error
$ node inspect app.js
Timeout (2000) waiting for 127.0.0.1:9229 to be free
No other terminals are open and I used netstat in the command terminal to see if the port is being used and it isn't.
you might have to configurate your chrome.
Open. chrome://inspect
in the Devices tab, click Configure, and them you will see the target Discovery settings.
Add, 127.0.0.1:9229 or all another ports you might have, in my case I added 127.0.0.1:9222 as well.
I had the same problem, I found a git issue on node-inspect that gives a solution that worked for me. Apparently the problem is the timeout on opening the ports. The solution is to increase the timeout in the executable.

The instructions are basically opening the node.exe in a hex editor, find the portIsFree string and change the timeout from 2000 to something larger.
