I’m new to vps hosting and my website is hosted on digitalocean, I’m using ratchet library ( for my php application. It’s working on localhost but not in server.


    use Ratchet\Server\IoServer;
    use Ratchet\Http\HttpServer;
    use Ratchet\WebSocket\WsServer;
    use MyApp\Chat;

        require dirname(__DIR__) . '/vendor/autoload.php';

        $server = IoServer::factory(
            new HttpServer(
                new WsServer(
                    new Chat()


In my client side code:

           var conn = new WebSocket('wss://');

In my nginx configuration file (/etc/nginx/sites-available/

 server {
        root /var/www/;

        index index.html index.htm index.php;

        location / {
            try_files $uri $uri/ =404;

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

        location ~ /\.ht {
            deny all;

        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    server {
        if ($host = {
            return 301 https://$host$request_uri;
        } # managed by Certbot

        if ($host = {
            return 301 https://$host$request_uri;
        } # managed by Certbot

        listen 80;
        return 404; # managed by Certbot


In my console it says

“WebSocket connection to ‘wss://’ failed: Error during WebSocket handshake: Unexpected response code: 200”

note: my domain has ssl. I’m new to this stuff, can somebody please guide me.

Thanks in advance!
