Rails server не видит изменений кода и перезагрузки файлов

я заметил, что мой сервер rails не перезагружает контроллеры, модели и, вероятно, любые другие файлы после их изменения. Я использую Vagrant и Rails API, и я обнаружил, что некоторые люди исправляют эту проблему, добавляя ниже строку в Vagrantfile.

config.vm.provider "virtualbox" do |vb|
  vb.customize [ "guestproperty", "set", :id, "/VirtualBox/GuestAdd/VBoxService/--timesync-set-threshold", 5000 ]
end

это не решает проблему для меня. Я бегу из идеи, что еще я могу сделать, чтобы решить эту проблему. Я прикрепляю файлы, которые могут быть вам полезны.

мой Gemfile выглядит так:

source 'https://rubygems.org'

gem 'rake', '< 11.0'

Я уверен, что что я запускаю свой сервер в режиме разработки, из-за начала журнала

=> Booting Puma

мой Vagrantfile
