Travis / Scrutinizer / Laravel: ErrorException: file_get_contents (http://localhost/api/v1/public-ip): не удалось открыть поток: соединение отклонено

Question

Я вызываю свой собственный API (проект на основе Laravel).

В локали все работает, с Travis / Scrutinizer у меня эта ошибка:

ErrorException: file_get_contents(http://localhost/api/v1/public-ip): failed to open stream: Connection refused

Это мой .travis.yml файл

language: php

php:
  - 7.2
#mysql:
  #- 5.7
node:
  - 8.1

branches:
  only:
    - master
    - develop

before_script:
  #- touch database/database.sqlite
  #- mysql -u root -e 'CREATE DATABASE IF NOT EXISTS test;'
  - rm .env.testing
  - cp .env.ci .env
  - cp .env.ci .env.testing
  - composer self-update
  - composer install --no-interaction
  - chmod -R 777 storage
  - chmod -R 777 bootstrap/cache
  - rm -rf node_modules
  - npm install
  - npm run production
  - php artisan key:generate
  - php artisan serve &

script:
  #- php artisan migrate:refresh --seed --no-interaction -vvv #This will clean, migrate, then seed the db
  - vendor/bin/php-cs-fixer fix app --dry-run --rules=@PSR2
  - vendor/bin/phpunit --testdox
