URI redirect error

[TheRealStriff]

Tested this, and getting a URL redirect error.
(Similar to what we were getting with Nintex)

Sorry, but we’re having trouble with signing you in.

AADSTS50011: The redirect URI 'http://localhost:63958' specified in the request does not match the redirect URIs configured for the application 'XXXXXX'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal

thanks
