Server logs: "Connection Established" but client does not receive pusher:connection_established

Reverb Version

1.4.1

Laravel Version

11.27.2

PHP Version

8.3.12

Description

When changing Laravel Websockets from Beyondco to Laravel Reverb. I have the problem described in the title: Laravel reverb logs "Connection Established" but the client does not receive this. After some time the client will give a "WebSocket was closed before the connection was established" error. The Laravel Reverb server does not seem to throw an error of some kind. It just logs that the "Connection Closed".

Steps To Reproduce

Start a new Laravel project

Add Laravel reverb For the port we use 6001 which was also used for Laravel Websockets Nginx:


location ws {
    proxy_pass                          http://127.0.0.1:6001;
    proxy_set_header Host               $host;
    proxy_set_header X-Real-IP          $remote_addr;

    proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto  https;
    proxy_set_header X-VerifiedViaNginx yes;
    proxy_read_timeout                  60;
    proxy_connect_timeout               60;
    proxy_redirect                      off;

    # Specific for websockets: force the use of HTTP/1.1 and set the Upgrade header
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}
