Just installed on Ubuntu 18.04.01 SERVER. Cannot access the repo for the first time (404)

I just installed the product with the following commands:

$ sudo curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

$ sudo EXTERNAL_URL=”http://gitlab.idsm.it” apt-get install gitlab-ce

on the /etc/gitlab/gitlab.rb I have the followinf lines:

git_data_dirs({
  "default" => {
    "path" => "/git/git-data"
  }
})

and

external_url 'http://gitlab.idsm.it'

but, when I try to connect for the first time, I receive the following error:
