title: Api call returns invalid region (US) when trying to compile app for deployment to Heroku despite having set the region to EU
body: <p>I am trying to deploy my application to Heroku. I am using an external api which is blocked for the region US. I therefore created my application with the region eu with Heroku.</p>
  
  <p>Despite this I still get back a 300 response rerouting to a page stating that I try to access the API from the US which is a blocked region. Any idea why this still happens despite having set the region to EU? Are there any solutions or add ons for this?</p>
  
  <p>Edit: the API call is made from the Ruby back end using the Faraday gem
  Edit: heroku info shows that the region is correctly set to eu</p>
