移動していませんでした..!
移動してrails sを実行したら以下のように出力されたのですが、まだ接続できません。。

$ rails s
=> Booting Puma
=> Rails 6.0.0 application starting in development
=> Run `rails server --help` for more startup options
RAILS_ENV=development environment is not defined in config/webpacker.yml, falling back to production environment
