HTTP 400 483 с Apache ProxyPassMatch и RewriteCond

Я все время получаю сообщение об ошибке:

apache_1_da0b6d97082f | 172.24.0.1 - - [16/Sep/2019:15:58:52 +0000] "GET /logi HTTP/1.1" 400 483 "-" "curl/7.64.0"

Но я не знаю почему? Похоже, что запрос не проходит через сокет php-fpm.

ServerName mainapp.local

<VirtualHost *:80>
    ServerName mainapp.local

    DocumentRoot /var/www/html/public/
    CustomLog /dev/stdout combined
    LogLevel debug

    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php [L,QSA]

    ProxyPreserveHost On
    ProxyPassMatch "^/(.*\.php(/.*)?)$"           "unix:/this/path/does/not/matter.sock|fcgi://localhost/var/www/html/public"

    <Directory "/var/www/html">
        Options +Indexes +FollowSymLinks +IncludesNOEXEC -MultiViews
        AllowOverride All
        Require all granted
        DirectoryIndex index.php
    </Directory>

</VirtualHost>

Он работает правильно (HTTP 200) без директив Rewrite , но, очевидно, мне нужна эта функция.

Если я enable Перезапись отладки LogLevel: trace8 :
