Can't receive broadcasted message from laravel echo server

In laravel-echo-console:

L A R A V E L  E C H O  S E R V E R

version 1.5.2

⚠ Starting server in DEV mode...

✔  Running at localhost on port 6001
✔  Channels are ready.
✔  Listening for redis events...

Server ready!

[7:07:00 PM] - YSTAl2zDJP0HtuoCAAAA joined channel: public
[7:07:00 PM] - Sending auth request to: https://xxxxx/broadcasting/auth

[7:07:00 PM] - YSTAl2zDJP0HtuoCAAAA authenticated for: private-survey.2
[7:07:00 PM] - YSTAl2zDJP0HtuoCAAAA joined channel: private-survey.2


Channel: laravel_database_private-survey.2
Event: server.message

All looks fine, but I can't recieve this message in browser:

window.Echo.private('survey.2')
 .listen('.server.message', (e) => {
        console.log(e)  
});
e {events: {…}, name: "private-survey.2", socket: p, options: {…}, eventFormatter: t}

My event class:

   public function __construct($message)
    {
        $this->message = $message;
    }

    public function broadcastOn()
    {
        return new PrivateChannel('survey.2');
    }

    public function broadcastAs()
    {
        return 'server.message';
    }

In laravel telescope I see:

{
  message: "wdfwsfwf",
  socket: null
}

does it normal that socket is null? Also always 0 listeners for this event.

What's wrong?

my problem was here Channel: laravel_database_ private-survey.2 change this in config/database.php

echo must join to "survey.2" in this case

if broadcasAs

 public function broadcastAs()
    {
        return 'server.message';
    }

echo must listen ".server.message" - dot before says not using namespace - this is event - not channel!
