AWS 本番環境でBootstrapが反映されない

Question

##環境

herokuにデプロイしていたアプリをAWS ec2に移行しています。デプロイにはcapistranoを使っています

Amazon Linux 2
RDS
ruby 2.7.1p83
Rails 6.0.3.4
nginx　1.18.0
puma 4.3.7
mysql Ver 8.0.22 for Linux on x86_64 (MySQL Community Server - GPL)
capistrano 3.14.1

##やったこと

こちらの記事に沿って作業をしたのですが、全体的に理解が薄く、てこずっています。

ブラウザからURLを打ち込んでアクセスすることはできるようになったのですが、Bootstrapが反映されておらずレイアウトが崩れてしまっています。
sshでec2に入り、/var/www/アプリ名/current/publicをみると、開発環境のapp/assets/imagesとstylesheetsのファイルは確認できたので、コンパイルは成功しているようです。nginxとpumaのエラーログを見ても問題の原因が分からず立ち往生しています。
お力をお貸しください。

##参考
解決のため参考になりそうなファイルをいくつかあげます。

/etc/nginx/cof.d/アプリ名.conf

upstream puma_アプリ名.conf { 
  server unix:/var/www/アプリ名/shared/tmp/sockets/puma.sock fail_timeout=0;
}

  keepalive_timeout 10;

  error_page 500 502 504 /500.html;
  error_page 503 @503;

  location @puma_アプリ名.conf {

  }

  location ^~ /assets/ {
    root   /var/www/アプリ名/current/public;
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  location = /50x.html {
    root html;
  }

  location = /404.html {
    root html;
  }

  location @503 {
    error_page 405 = /system/maintenance.html;
    if (-f $document_root/system/maintenance.html) {
      rewrite ^(.*)$ /system/maintenance.html break;
    }
    rewrite ^(.*)$ /503.html break;
  }

  if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$ ){
    return 405;
  }

  if (-f $document_root/system/maintenance.html) {
    return 503;
  }
}

を追記してデプロイしなおしたらBootstrapが反映しました。
