You set the port to 8080 for the URL? or your app?

yes i set

listen 8080;
in railway-nginx.conf

OP can also map the URL to the designated port via service settings.

I Added PORT Variable in Variable of App Service Value is 8080

but not work but not work yet

this is my railway-nginx.conf

server {
    listen 8080;
    server_name _;
    root /var/www/html/public;

    index index.php index.html;

    # Add server tokens off for security
    server_tokens off;

    #  gzip
    gzip on;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

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

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_buffering off;
        fastcgi_read_timeout 300;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }

    # Store Static Files
