i need help to fix that error i set port as 8080 as the must be but not thing solve it

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

yes i set

listen 8080;
in railway-nginx.conf

if you manually set listen 8080; inside your config file you have to make sure railway knows to look for traffic there

go to your service Variables tab in the dashboard and add this environment variable

PORT with the value 8080

if you dont set that railway might be assigning a random port number to the environment that your nginx isnt listening on which causes the 502

if that doesnt fix it check your Deploy Logs and paste the error output here using a code block

paste logs here

sometimes nginx crashes on startup if the config syntax is wrong so the logs will tell us exactly whats up

hope that helps

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
    location ~* \.(jpg|jpeg|png|gif|ico|css|js|svg|woff|woff2|ttf|eot)$ {
        expires 30d;
        add_header Cache-Control "public, immutable";

i don't know why i still get that error status code 502

here also deploy log Starting Container

hey @bmask2020 thanks for pasting those logs.

i think i see the issue. looking at the deploy logs in reply #9, it shows the database migrations running successfully... but then it just stops.

Creating migration table ...................................... 17.14ms DONE

i don't see any logs saying that Nginx or PHP-FPM actually started up. if your container finishes the migrations and doesn't explicitly start the web server processes, Railway won't have anything to connect to, which gives you that 502 Bad Gateway.

since you installed supervisor in your build process (saw it in reply #7), your startup script needs to trigger that to keep the app running.

can you paste the content of your start.sh file here?

we need to make sure it looks something like this at the end:

# ... migration commands ...

# start supervisor (or php and nginx)
/usr/bin/supervisord -c /etc/supervisord.conf

without seeing that file it's hard to know if the server is actually booting up.

also shoutout to @0x5b62656e5d for the port tip earlier, that part looks correct now in the nginx config. we just need to get the processes running.
