This looks like a route issue. If you do "rake routes | grep auth" what do you see?

I had exactly the same problem you described. Make sure you require the omniauth-google-oauth2 gem in config/initializers/deviser.rb

# ==> OmniAuth # Add a new OmniAuth provider. Check the wiki for more information on setting # up on your models and hooks. require "omniauth-google-oauth2" config.omniauth :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"], { access_type: "offline", approval_prompt: "force" }

I've added the entire portion of my devise.rb file to provide context.

It's very late but this answer might be useful for others

If you are using devise for authentication then devise by default generates routes in the route file devise_for :users and your omniouth_callback route should be above the default devise route so that it overwrites default devise route.

 devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks"} devise_for :users
