Issue with login after deploy

I wonder if anyone can help me with a query.

I just migrated an older (2.1) refinery cms app to 3.0 and added Refinerycms authentication devise and adapted the relevant changes including migrations.

I ran the production version of the app locally for testing and all works well. I can login as myself; create new users; and login as them too.

After I deployed the app into production, i can never login to the admin section. I kept being redirected back to the login screen despite the logs indicating I have logged in successfully:

The UPDATE action indicates that i have logged in hence the sign_in count has also increased. yet I kept being redirected back?

Can anyone shed some light on this? I tried to create the same production environment locally as the remote app and I cannot work out the issue.

Thank You.
