Rails Production log dont update - ruby-on-rails

Question

I'm using Rails 6.0.3
In production I try to run a tail -f on the production log and I don't receive updates when I do any action on the application. Any idea?
I tried to apply 0644 permissions to the production.log file, but that's not the problem, because there is data in the file.
I am using nginx and puma too.
Production Log:
Production log file permissions
-rw-rw-r-- 1 ubuntu ubuntu 733 Apr 25 11:44 production.log
production.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests.
config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both threaded web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true
# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
# Ensures that a master key has been made available in either ENV["RAILS_MASTER_KEY"]
# or in config/master.key. This key is used to decrypt credentials (and other encrypted files).
# config.require_master_key = true
# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
# Store uploaded files on the local file system (see config/storage.yml for options).
config.active_storage.service = :local
config.cache_store = :redis_cache_store, { url: "redis://localhost:6379/0" }

# config.force_ssl = true
# Use the lowest log level to ensure availability of diagnostic information
# when problems arise.
config.log_level = :debug
# Prepend all log lines with the following tags.
# config.log_tags = [ :request_id ]
# Use a different cache store in production.
# config.cache_store = :mem_cache_store
config.action_mailer.perform_caching = false
# Ignore bad email addresses and do not raise email delivery errors.
# Set this to true and configure the email server for immediate delivery to raise delivery errors.
# config.action_mailer.raise_delivery_errors = false
............
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation cannot be found).
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify
# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter = ::Logger::Formatter.new
# Do not dump schema after migrations.
config.active_record.dump_schema_after_migration = false
end
Thanks in advance.

I solved my problem by adding these lines to my production file:
config.logger = Logger.new (Rails.root.join ("log / production.log"))
And restarting the cougar on the production server.
