为什么 nginx.conf 返回“GET /index.php” 404”？

Question

我正在尝试在 Docker 中配置 nginx 配置，但是当我启动“sudo docker-compose up -d”并尝试连接到“http://localhost:8098/”时，我看到：找不到文件。 和日志如下：

docker-infrastructure_php-fpm_1 | 172.19.0.3 -  03/Mar/2022:21:35:35 +0000 "GET /index.php" 404
docker-infrastructure_nginx_1 | 172.19.0.1 - - [03/Mar/2022:21:35:35 +0000] "GET / HTTP/1.1" 404 27 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36" "-"`

有我的： nginx.conf

server {
    listen 80;
    server_name dgtips-backend-local;
    root /home/sergey/PhpstormProjects/dgtips-backend/public;
    index index.php;

    location / {
        try_files $uri /$uri /index.php?$query_string;
    }

    location ~ [^/]\.php(/|$) {

        fastcgi_param SCRIPT_FILENAME /home/sergey/PhpstormProjects/dgtips-backend$fastcgi_script_name;
        fastcgi_pass php-fpm:9000;
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
    }
}

nginx.Dockerfile

FROM nginx

ADD docker/nginx/nginx.conf /etc/nginx/conf.d/default.conf

WORKDIR /home/sergey/PhpstormProjects/dgtips-backend/public

docker-compose.yml

version: "3.3"

services:
    nginx:
        build:
          context: .
          dockerfile: docker/nginx/nginx.Dockerfile
        ports:
            - 8098:80
        volumes:
          - ./:/home/sergey/PhpstormProjects/dgtips-backend
        links:
          - php-fpm
    php-fpm:
        build:
            context: .
            dockerfile: docker/php-fpm/fpm.Dockerfile
        volumes:
          - ./:/home/sergey/PhpstormProjects/dgtips-backend

最后 fpm.Dockerfile

FROM php:7.4-fpm

RUN apt-get update \
&& docker-php-ext-install pdo pdo_mysql

我完全确定我的（本地）项目和 index.php 文件的路径正确
