I am working on a Rails application which is in development mode and it can register with omniauth.
The host is
http://localhost:3000/
Issue: Oauth2 Instagram API “redirect URI does not match registered redirect URI
My Solution: Please check ng-cordova-oauth.js file and check instagram function in that. Verify redirect_uri value is same as register your application on developer console for Instagram.If it is same it works properly,otherwise you get the above issue.
