Redirect_URI not resolving correctly

[mastari]

Steps to Reproduce

1. Change redirect_uri parameter to some value in config: config :ueberauth, Ueberauth.Strategy.Google.OAuth, redirect_uri: 'https://example.com'

2. Check network logs

Expected Result

Expected redirect_uri to be https://example.com

Actual Result

Got redirect_uri to be http://example.com

My Suspicion

My endpoint uses HTTP and I get HTTPS throught NGINX. I think the uri is resolving to the endpoint HTTP status instead of explicitly using the string I provided it.
