Hello all, I’m not to Jekyll and have successfully installed it on my Mac. When I run bundle exec jekyll build it works except I’m not able to see the site. I get a can’t connect to server.

My Gemfile is

# frozen_string_literal: true

source "https://rubygems.org"

git_source(:github) { |repo_name| "https://github.com/#{repo_name}" }

# gem "rails"
gem "jekyll"

and bundle update
