redirect_uri_mismatch

Problem/Motivation

Hi,
I could not make it to work. I receive redirect_uri_mismatch errors again and again... :-(

Steps to reproduce

- Created the keys
- Created the authman instance
- On github, created an Oauth App using https://[mydomain]/admin/config/authman/oauth/receiving/[authman_instance_machine_name] path

Help would be appreciated :-)

Regards,
Alexandre
