I am Unable to authenticate CKAN 2.7.2(running on https) using ckanext-oauth2 on WSO2 Identity Server

Hi
My setup configuration versions are

CKAN2.7.2.
WSOIS - 5.7
WSO2am - 2.6

I have update the ckanext-oauth2==0.7.0 extension at CKAN side. After updating the oauth2 version, I am unable to login on CKAN via wso2am. Earlier it was working fine. Is their any configuration changes are also required at wso2 side?
callback url is : https:/hostname/oauth2/callback

I am getting the below error :

**invalid_callback

Registered callback does not match with the provided url.**

@aarranz can you please help here.

The error says it all. The callback does not match. CKAN 2.7.x is also a quite old release, I would suggest upgrading.
