I have a Laravel app served through Traefik and an Nginx proxy.

This is my docker-compose file with the laravel service. My idea was to setup a subdomain on ws.v3.localhost for the Reverb requests and to have Traefik add the /ws prefix for Nginx to know how to handle these requests

  laravel:
(...)
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.laravel.entrypoints=web"
      - "traefik.http.routers.laravel.rule=Host(`ttfr.v3.localhost`)"
      - "traefik.http.middlewares.ws-prefix.addprefix.prefix=/ws"
      - "traefik.http.routers.laravel-ws.rule=Host(`ws.v3.localhost`)"
      - "traefik.http.routers.laravel-ws.middlewares=ws-prefix"
      - "traefik.http.services.laravel-ws.loadbalancer.server.port=80"

Then I have this nginx config file,

server {
    listen 80;

    index index.php index.html;

    charset utf-8;

    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;

    root /var/www/app/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-Content-Type-Options "nosniff";
    add_header 'Content-Security-Policy' 'upgrade-insecure-requests';
    add_header 'Access-Control-Expose-Headers' 'X-Inertia';

    location /ws/ {
        proxy_http_version 1.1;
        proxy_set_header Host $http_host;
        proxy_set_header Scheme $scheme;
        proxy_set_header SERVER_PORT $server_port;
        proxy_set_header REMOTE_ADDR $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";

        access_log /var/log/nginx/ws_access.log;
        error_log /var/log/nginx/ws_error.log;

        proxy_pass http://localhost:8088;
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
        proxy_set_header X-Forwarded-Proto https;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

    location ~ .php$ {
        fastcgi_pass localhost:9000;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

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

The reverb server is running on 0.0.0.0:8088

If I bind the ports from the container in my docker-compose config (8088:8088), the app is able to send the Reverb requests directly to localhost:8088 and it works. But when I use the config above and I set up these values in my .env, it does not work anymore.

REVERB_HOST=ws.v3.localhost
REVERB_PORT=80
REVERB_SCHEME=http

REVERB_SERVER_HOST=0.0.0.0
REVERB_SERVER_PORT=8088

Does my approach make sense? Is there something I’m missing? I’d appreciate any tips on how to debug this and identify where the problem comes from.
