Can's access root in Docker Nginx

Hi Docker Pros, I can’t access to my root folder with port http request. It shows 404 not found, nginx/1.19.6. Docker compose working fine with local windows docker engine, but requesting same port can’t seem to access root folder on my VPS. How do I troubleshoot nginx conf problem?

default.conf

version: '3'

services:

    web:

        image: nginx:alpine

        volumes:

            - "./etc/nginx/default.conf:/etc/nginx/conf.d/default.conf"

            - "./etc/ssl:/etc/ssl"

            - "./web:/var/www/html"

            - "./etc/nginx/default.template.conf:/etc/nginx/conf.d/default.template"

        ports:

            - "8000:80"

            - "3000:443"

        environment:

            - NGINX_HOST=${NGINX_HOST}

        command: /bin/sh -c "envsubst '$$NGINX_HOST' < /etc/nginx/conf.d/default.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"

        restart: always

        depends_on:

            - php

            - mysqldb

    php:

        image: nanoninja/php-fpm:${PHP_VERSION}

        restart: always

        volumes:

            - "./etc/php/php.ini:/usr/local/etc/php/conf.d/php.ini"

            - "./web:/var/www/html"
