Problem connecting to Laravel Websockets from React Native

Question

I'm having problems with Laravel Websockets. I build a chat app using Laravel Websockets, Vue.JS and Laravel-Echo. The web app works correctly, so I started working in a Mobile version with React Native, but I can't connect to private/presence channels.

I can connect to public channels withour problems. I have the following code:

    useEffect(() => {
        const echo = new Echo({
            broadcaster: 'pusher',
            key: 'pusher-app-key',
            cluster: 'mt1',
            wsHost: 'my-domain.com',
            wsPort: 6001,
            wssPort: 6001,
            encrypted: true,
            forceTLS: false,
            enabledTransports: ['ws', 'wss'],
            authEndpoint: 'https://my-domain.com/broadcasting/auth',
            auth: {
                headers: {
                    Authorization: authToken,
                },
            },
        });

        const channel = echo.private(channelUri);
        channel.subscribed(() => {
            console.log("connected");
        }).listen(eventName, (event) => {
            console.log(event);
        }).error((error) => {
            console.log(error);
        });
    }, []);

If I change my channel URI to a public one, it connects and I can listen to events without problems. But, using the same configuration for a private channel, I can not connect. I got the following error:

{"error": "Unable to retrieve auth string from channel-authorization endpoint - received status: 403 from https://my-domain.com/broadcasting/auth. Clients must be authorized to join private or presence channels. See: https://pusher.com/docs/channels/server_api/authorizing-users/", "status": 403, "type": "AuthError"}

I am sending my Bearer token in Authorization like this: "Bearer ${token}" and it works for HTTP requests, it is not expired.

Other stuff tried: -CORS configuration -SSL is configured, web app is working.

Any suggestions that I could try? Thanks a lot.
