That's the message I get when I try to run http://localhost:3000. I currently have WAMP running a local server on localhost so don't know if that could be causing some sort of conflict. Tried running it on https but got the same error.
Hi,
One way to inspect your local app is to use bookmarklet. To add bookmarklet,
1. In Inspector, click on the button "Quick connect an app with Bookmarklet"
2. Drag the blue "Sencha Inspector bookmarklet" button to your browser bookmarks bar
3. Now open your local ExtJS app in your browser and click on the bookmarklet in bookmarks bar.
4. You should see you app in Inspector. More details are at http://docs.sencha.com/tools/sencha_...lications.html
