I am following instruction for creating application from getting-started(<https://developers.google.com/+/hangouts/getting-started>) document but while setting application url for Google hangout Application configuration in google console, I am getting always same error 'The user request is invalid. Please check your URL and try again.'

I have tried google default xml(<https://developers.google.com/+/hangouts/getting-started>) file url for Application URL which is given in same document but still not able to save it's configuration with this url.

I am using correct xml file but still facing Application URL issue? .. Is anyone have any idea for saving Google hangout Application configuration in google api console
