Capistranoを導入して自動デプロイしたがURLでアクセスできない

起きていること

下記のサイトを参考にCapistranoの導入まで行いました。自動デプロイはエラーなく完了したのですがいざURL（http:// 3.115.231.1）でアクセスしてみると「このサイトにアクセスできません3.115.231.1 で接続が拒否されました。」と出てしまします。
何が原因なのでしょうか。

config/deploy/production.rb

# server-based syntax
# ======================
# Defines a single server with a list of roles and multiple properties.
# You can define all roles on a single server, or split them:

# server "example.com", user: "deploy", roles: %w{app db web}, my_property: :my_value
# server "example.com", user: "deploy", roles: %w{app web}, other_property: :other_value
# server "db.example.com", user: "deploy", roles: %w{db}



# role-based syntax
# ==================

# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.

# role :app, %w{deploy@example.com}, my_property: :my_value
# role :web, %w{user1@primary.com user2@additional.com}, other_property: :other_value
# role :db,  %w{deploy@example.com}



# Configuration
# =============
# You can set any configuration variable like in config/deploy.rb
# These variables are then only loaded and set in this stage.
# For available Capistrano configuration variables see the documentation page.
# http://capistranorb.com/documentation/getting-started/configuration/
# Feel free to add new variables to customise your setup.



# Custom SSH Options
# ==================
# You may pass any option but keep in mind that net/ssh understands a
# limited set of options, consult the Net::SSH documentation.
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start
#
# Global options
# --------------
#  set :ssh_options, {
#    keys: %w(/home/user_name/.ssh/id_rsa),
#    forward_agent: false,
#    auth_methods: %w(password)
#  }
#
# The server-based syntax can be used to override options:
# ------------------------------------
# server "example.com",
#   user: "user_name",
#   roles: %w{web app},
#   ssh_options: {
#     user: "user_name", # overrides user setting above
#     keys: %w(/home/user_name/.ssh/id_rsa),
#     forward_agent: false,
#     auth_methods: %w(publickey password)
#     # password: "please use keys"
#   }
# サイトを参考にした記述

環境についての情報を追記してください。また、設定ファイルに合わせて各種ログを確認してください。 Rails、UnicornはもちろんWebサーバのログ（書いてないですがnginx？）等。ログを見ればどこでエラーになったかが出ている可能性が高いため、まず確認すべきはエラー時に何が発生しているかです。

ありがとうございます。Nginx使っております。ただNginxのアクセスログを確認すると下記のように出てきてします状況です。 [ec2-user@ip-172-31-35-175 portfolio]$ tail -f /var/log/nginx/access.log tail: `/var/log/nginx/access.log' を読み込み用に開くことが出来ません: 許可がありません tail: ファイルが全く残っていません参考サイトでCapistrano導入する直前まではサイトにアクセスできたので、Capistranoの導入時に何か原因ができてしまったのではと思っております。

権限不足と思われるので sudo 〜でコマンド実行するか、access.logの権限を変更してください

また、nginxのログ「だけではなく」Rails,Unicornのログも確認してください。

ありがとうございます。Rails,Nginxのログは確認方法わからずまだなのですが、Unicornは確認できましたので貼り付けます。長かったのでエラーが出てそうな箇所だけ抜粋しました。 E, [2020-09-22T10:41:22.100582 #884] ERROR -- : worker=0 PID:928 timeout (61s > 60s), killing E, [2020-09-22T10:41:22.104346 #884] ERROR -- : reaped #<Process::Status: pid 928 SIGKILL (signal 9)> worker=0 I, [2020-09-22T10:41:22.106930 #930] INFO -- : worker=0 ready /home/ec2-user/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/unicorn-5.4.1/lib/unicorn/http_server.rb:205:in `pid=': Already running on PID:884 (or pid=/var/www/portfolio/tmp/pids/unicorn.pid is stale) (ArgumentError) from /home/ec2-user/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/unicorn-5.4.1/lib/unicorn/http_server.rb:137:in `start' from /home/ec2-user/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/unicorn-5.4.1/bin/unicorn_rails:209:in `<top (required)>' from /home/ec2-user/.rbenv/versions/2.7.1/bin/unicorn_rails:23:in `load' from /home/ec2-user/.rbenv/versions/2.7.1/bin/unicorn_rails:23:in `<main>' I, [2020-09-22T11:55:54.717624 #884] INFO -- : reaped #<Process::Status: pid 930 exit 0> worker=0 I, [2020-09-22T11:55:54.717815 #884] INFO -- : master complete I, [2020-09-22T11:56:04.292608 #1468] INFO -- : Refreshing Gem list
