Node Debug From Vagrant

Question

Unable to remote debug a node server running on a Vagrant box in Chrome from my host machine. The server is configured to run on port 8123.

Node Version: 7.10.0

In Vagrantfile:

config.vm.network :forwarded_port, host: 9229, guest: 9229
config.vm.network :forwarded_port, host: 8123, guest: 8123

From my vagrant box I run:

$ node --inspect index.js
Debugger listening on port 9229.
Warning: This is an experimental feature and could change at any time.
To start debugging, open the following URL in Chrome:
chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:9229/84085f07-dc42-4e1e-bdd8-532e6dc5c4c6
--- Customer Service---
Connecting to customer repository...
Connected. Starting server...
Server started successfully, running on port 8123.

When I try to access the url in Chrome from my host machine while I don't get an error the sources tab is empty.

Based on NodeJS 11591 issue. You can't access the Vagrant stuff via localhost (127.0.0.1), so you need to to specify host explicitly:

$ node --inspect=0.0.0.0:9229 index.js

Then you need to set up Target discovery settings in the Chrome. Note that 192.168.33.11 from my sample is the static IP address providing an access to the Vargant host from the local host:
