Bundle Install could not fetch specs from https://rubygems.org/

I'm attempting to follow the Hartl Rails Tutorial, and having trouble with the bundler gem.

When using the commands 'bundle install' or 'bundle update' I get the following output:

Fetching source index from https://rubygems.org/

Could not fetch specs from https://rubygems.org/

I've searched for this output, but did not find many related issues online.

Maybe I have another gem that is interrupting bundler? I have little experience with rails at this point.

    source 'https://rubygems.org'

gem 'rails', '3.2.12'

group :development do
  gem 'sqlite3', '1.3.5'
end


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'

  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

The solution for me was two parts: I changed https to http, and that temporarily solved the issue. The second issue was that I think I had a bad install of ruby 2.0.0 even though I was using a fresh install of ruby 1.9.3. So I reinstalled ruby 2.0.0, and I could use bundle install with https.
