Slim框架API部署后出现404 NotFound错误求助

我正在开发毕业设计的Android应用，本地开发流程完全顺畅，但通过Filezilla将API文件上传至服务器后，持续出现404 NotFound错误。尝试修改.htaccess文件中的RewriteBase配置后问题仍未解决，不确定是否存在配置错误。相关代码及错误信息如下：

public/index.php #

<?php

use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Factory\AppFactory;

require '../vendor/autoload.php';
require '../includes/DbOperations.php';

$app = AppFactory::create();
$app->setBasePath("/mylife/public");
$app->addErrorMiddleware(true, true, true);

// My routes
// ...

$app->run();

.htaccess文件配置 #

我在public文件夹内外各放置了一个.htaccess文件：

外层（public文件夹外）.htaccess #

Options All -Indexes

<Files .htaccess>
order allow,deny
deny from all
</Files>

<IfModule mod_rewrite.c>
  # Redirect to the public folder
  RewriteEngine On
  RewriteBase /mylife/
  RewriteRule ^$ public/ [L]
  RewriteRule (.*) public/$1 [L]

  # Redirect to HTTPS
  # RewriteEngine On
  # RewriteCond %{HTTPS} off
  # RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

内层（public文件夹内）.htaccess #

Options All -Indexes

<Files .htaccess>
order allow,deny
deny from all
</Files>

<IfModule mod_rewrite.c>
  RewriteEngine On

  # Redirect to HTTPS
  # RewriteEngine On
  # RewriteCond %{HTTPS} off
  # RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

  # Some hosts may require you to use the `RewriteBase` directive.
  # Determine the RewriteBase automatically and set it as environment variable.
  # If you are using Apache aliases to do mass virtual hosting or installed the
  # project in a subdirectory, the base path will be prepended to allow proper
  # resolution of the index.php file and to redirect to the correct URI. It will
  # work in environments without path prefix as well, providing a safe, one-size
  # fits all solution. But as you do not need it in this case, you can comment
  # the following 2 lines to eliminate the overhead.
  RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
  RewriteRule ^(.*) - [E=BASE:%1]
  
  # If the above doesn't work you might need to set the `RewriteBase` directive manually, it should be the
  # absolute physical path to the directory that contains this htaccess file.
  # RewriteBase /

  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^ index.php [QSA,L]
</IfModule>

测试情况 #

测试路径：https://ruangprojek.com/sadiahcafe/mylife/public/allmenu

正常情况下API可访问时会返回参数缺失等其他错误，但当前始终返回404。已尝试修改链接、Base URL、.htaccess配置及数据库，均未解决问题；本地环境运行正常，文件名称也无大小写问题。
