Capybara::Poltergeist::StatusFailError: failed to reach server

[Benny Paulino]

I'm new to using Poltergeist. Attempts to resolve hostname issues for the call to root_url(...) have been commented out in the relevant files below. These approaches and the current state are met with the following error:

Issue...
