What do I need to set my redirect URI to in order to get the web AppBuilder to work?

[HayleyHames]

I keep getting an invalid redirect_uri when I try to start up the appbuilder application I keep getting an redirect_uri invalid error.  Is there some sort of system for generating what this uri should be?  The app is hosted using our ArcGIS online organization account.

Thanks.

Have you tried setting up both http://[yourmachinename]and https://[yourmachinename] ?

I just had the same problem before... hope it helps

Thank you! I didn't set up both, just one. I really need to learn to read.
