If you get the “Could not connect to the server” error running you project from Netbeans while script/server works fine, first make sure you have the correct Rails version set for your project, it should show “Installed version: 2.2.2”:

If you still get:

Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update –system` and try again.

But the suggested

gem update —system

often fails to update your gem to the new version so try

sudo gem install rubygems-update

and then run:

sudo gem install rubygems-update

and check with

gem -v

where it should show 1.3.1 at the time of writing.
