Reverb error

Hey foks so I am trying to use reverb but running into this issue.

The event triggers and in the logs I see this:

Couldn't connect to server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:8080/apps/673429/events?auth_key=****&auth_timestamp=1748544859&auth_version=1.0&body_md5=a416d1caedd8832364d5a753e8bca398&auth_signature=e151e0551da399991114ba2b10572403d12087ed29ec68eedba5f2089920b281.

My browser is able to connect to the server

{"event":"pusher:connection_established","data":"{\"socket_id\":\"863642737.836216913\",\"activity_timeout\":30}"}	114	
11:51:20.794
{"event":"pusher:subscribe","data":{"auth":"","channel":"tracker-created"}}	75	
11:51:20.821
{"event":"pusher_internal:subscription_succeeded","data":"{}","channel":"tracker-created"}

My nginx config file

server {
    listen 80;
    index index.php;
    server_name localhost;
    root /var/www/html/public;
 
    location / {
        try_files $uri $uri/ /index.php?$query_string;
        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";
 
        proxy_pass http://0.0.0.0:8080;
    }
 
    location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass ar_php:9000;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    }
 
}

My front-end code

Echo.channel('tracker-created')
    .listen('TrackerCreated', (e) => {
        console.log('TrackerCreated event received:');
    });

My env file

BROADCAST_CONNECTION=reverb
REVERB_APP_ID=****
REVERB_APP_KEY=****
REVERB_APP_SECRET=****
REVERB_HOST="localhost"
REVERB_PORT=8080
REVERB_SCHEME=http

#vite
VITE_REVERB_APP_KEY=${REVERB_APP_KEY}
VITE_REVERB_HOST=${REVERB_HOST}
VITE_REVERB_PORT=${REVERB_PORT}
VITE_REVERB_SCHEME=${REVERB_SCHEME}

What am I doing wrong?

Based on your description and logs, the error:

Couldn't connect to server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:8080/apps/673429/events?auth_key=...

means that your Laravel backend (when broadcasting events) cannot reach the Reverb server at localhost:8080. Even though your browser can connect, PHP (running inside your container or on your host) may not be able to.

This is a common issue when using Docker or similar setups. Here’s how to debug and solve it:

1. Check Where Laravel is Running

If Laravel is running in a Docker container, localhost refers to the container itself, not your host machine.
If Reverb is running on your host, you need to use the host's network IP, not localhost.

2. Solution: Use the Correct Host

If using Docker for Laravel:

Change your .env:

REVERB_HOST=host.docker.internal

host.docker.internal is a special DNS name that resolves to the host machine from inside Docker containers (works on Docker Desktop for Mac/Windows, and recent Docker for Linux).

If not using Docker:

Make sure Reverb is running and listening on localhost:8080.
From your terminal, try:
```
curl http://localhost:8080
```
If you get a response, the server is up.

3. Check Firewall and Bind Address

Make sure Reverb is listening on 0.0.0.0:8080 (not just 127.0.0.1:8080) if you want it accessible from other containers or machines.
In your Reverb config, set:
```
REVERB_HOST=0.0.0.0
```
and restart Reverb.

4. Update Your Frontend Vite Config

If you change the host, update your Vite variables as well:
```
VITE_REVERB_HOST=host.docker.internal
```

5. Restart Everything

After changing .env, run:

php artisan config:clear
php artisan cache:clear

6. Summary Table

Where Laravel Runs	Where Reverb Runs	REVERB_HOST Value
Host	Host	localhost
Docker	Host	host.docker.internal
Docker	Docker	reverb (service name)

Example: Docker Compose Setup

If both Laravel and Reverb are in Docker Compose, use the service name:

REVERB_HOST=reverb

Final Checklist

Ensure Reverb is running and accessible from where PHP runs.
Use the correct REVERB_HOST in your .env.
Clear Laravel config/cache after changes.
If using Docker, prefer host.docker.internal or the service name.

If you still have issues, please specify:

Are you using Docker for Laravel? For Reverb?
What OS are you on?
