railsチュートリアル9章でherokuエラーが起きる

Question

前提・実現したいこと

今Railsチュートリアルを、ローカル環境（mac)で作っており、9章の内容まで終わりました。
しかし、herokuにアップする時にエラーが起きてしまいました。
その対処法を教えて頂きたいです。

そして関係があるか分かりませんが、9章の途中からなぜか rails sを行うと、

         9: from /Users/abeshmupeii/Desktop/プログラミング/Rails系/ポートフォリオ/rails-site/vendor/bundle/gems/puma-5.5.2/lib/puma/runner.rb:155:in `load_and_bind'

(base) abeshmupeii@ABemcp rails-site % 

3000番が使われているという表記が出るのですが、
他のrails アプリでは、3000番は動くので、それが何か関係しているのではないかと考えています。
（原因は分かりません。）

もしくは、前のブランチに戻って作り直したいのですが、（8章の内容から）
git reset など使っても上手く戻れず、その戻り方のどちらかを教えて頂きたいです。

Answer 1

sslのコードが間違っていました。
