そのチュートリアル、よくherokuで動かないで未解決のママだから、チュートリアルの作者に見直してもらったほうがいいのでは

Answer 1

解決しました！
変更点

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        3001    || 3000
environment ENV['RACK_ENV'] || 'development'


on_worker_boot do

config/puma.rbのportを3001に指定してあげたこと
ログで出ていたのですが
何度もアプリケーションを立ち上げているようで
それぞれport番号も異なった状態で
Address already in use - bind(2) for "0.0.0.0" port xxxxxxと出ていました。

結論
rackupの設定のデフォルトが悪さして、port指定に失敗してたようです。
間違えていたらご指摘ください！????
