Capybara InfiniteRedirectError - ruby-on-rails

Question

I am getting the same behavior whether it's in the browser or running rspec... How can this issue get resolved?
I have tried removing the before_filter :authenticate_user! within application_controller.rb and the result remains the same. The failing example is the very first one within spec/features/subdomain_feature_spec.rb
Failures:
1) subdomains redirects invalid accounts
Failure/Error: visit root_url(subdomain: 'random-subdomain')
Capybara::InfiniteRedirectError:
redirected more than 5 times, check for infinite redirects.

The Capybara rack_test driver ignores hostnames so you're not going to be able to test subdomain behavior with it, you'll need to run those tests with one of the drivers that utilizes/mimics a full browser (selenium, poltergeist, capybara-webkit).
Additionally you want to write and url/path check using the Capybara have_current_path matcher rather than eq with `current_url'
expect(page).not_to have_current_path(/random-subdomain/, url: true)
