devise rails application redirecting to users/sign_in

all - New to rails and web development. I started a new rails application and am using Devise. Whenever I hit Log In on the users/sign_in page, the page just refreshes.

Here is my terminal log after clicking Log In. It's showing the POST, I'm not sure why it's ultimately rendering devise/sessions/new.html....:

    Started POST "/users/sign_in" for ::1 at 2017-10-02 09:19:20 -0400

My routes.rb

Rails.application.routes.draw do
  get 'charges/create'
  devise_for :users
  get 'welcome/index'
  get 'welcome/about'
  resources :wikis
  resources :charges, only: [:new, :create]
end

and my User.rb

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable
  has_many :wikis

  before_save { self.email = email.downcase }

  enum role: [:standard, :admin, :premium]
  after_initialize { self.role ||= :standard }

end

Thank you for any direction and please let me know if I can provide any more details / code samples etc.
