Grunt serve serves up blank page

[mhartington]

Grunt serve brings a blank page with an error

This webpage is not available

ERR_CONNECTION_REFUSED

While ionic serve works fine.
There are no errors in the build process so I'm not sure where the issue is.

Steps to reproduce:

Create a project without sass, standard plugins, no additional packages.

Refer #209
Downgrading grunt-concurrent to 1.0.0 should fix this issue

[yogesh-kamble]

I was having the same issue and to resolve I downgraded grunt-concurrent to 1.0.0
sudo npm uninstall grunt-concurrent
sudo npm install grunt-concurrent@1.0.0

[webspeaks]

Thanks, it worked.
Will it be fixed with newer versions of concurrent?

Thank you so much for this ! Lost some time hope this info filters into more mainstream as it appears to be an ionic/cordova thing perhaps or at least hard to get a clue on why it fails..

same issue. thanks to @niyando. it works now.
open browser and the application is up and running.

but it on port 8100! ....(why?). it should be 9000 because of 'connect' config in the Gruntfile.json ...am I right?

and one more question. will you update package.json file to have in devDependencies:
"grunt-concurrent": "^1.0.0",

?

thanks

@refactorman the connect task is used within the coverage task only, check the Gruntfile at the bottom. If you want to run ionic on another port you'll have to run it with grunt serve -p port_number, -p port_number is passed onto ionic-cli

Thank You! @JoaoGuedes
