gem \"rails\", github: \"rails/rails\"
         


        

Answer 1

The Blocked Host is a new feature of Rails 6. You can add this pattern to your config/environments/development.rb to have no worries of that in case of dynamic urls

config.hosts << /[a-z0-9]+\.c9users\.io/

Also for ngrok user, just replace above c9users by ngrok
