Thanks for the help. But it still runs at Port 8080, however instead of the app not working, when i open the window it says this Invalid Host header and that’s all…
However, I did manage to get the app running with this code:
webpack-dev-server --inline --progress --port 8080 --host 0.0.0.0 --config build/webpack.dev.conf.js --public $C9_HOSTNAME
Thanks to this forum link
