php-fpmでphpが表示されない

現在nginxを使いPHP-fpm から PHPアプリを表示しようと思い実装していますが、File not findと出ます
簡単な構成ですが、メインはRailsアプリになっており、サブディレクトリにPHPアプリを入れている形です

エラーログ
[error] 1874#0: *191 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 114.160.221.2, server: http://xxxxxx.com/, request: "GET /bank/ HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/www.sock:", host: "xxxxxxx.com"

    }
}

/etc/nginx/conf.d/php-fpm.conf

upstream php-fpm {
        server unix:/run/php-fpm/www.sock;
}

php-fpm側

/etc/php-fpm.d/www.conf

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[ec2-user]

user = nginx
group = nginx

listen = /run/php-fpm/www.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0666

現状の設定は上記のようになっております

エラーログからも読み取れるように、fastcgiが上手くできていないと思い


location ~ /bank/(.+.php)$ {
        alias          /home/ec2-user/environment/var/www/php/public/;
        fastcgi_pass   unix:/run/php-fpm/www.sock;
        fastcgi_index  index.php;
      - fastcgi_param  SCRIPT_FILENAME    /home/ec2-user/environment/var/www/php/public/$1;
      + fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
        include fastcgi_params;
        allow all;
    }

このように変更を加えてみたり、ディレクトリを変えてみたり等しました

同一ディレクトリ内のhtmlファイルは正常に表示されており、試しにphp-fpmをストップさせ
htmlを開いたときも正常に表示できていた為、php-fpm側に原因がありそうという状態です

どこの情報が必要か分からなかったので、現在操作している箇所をあげさせてもらってます
