连接wss协议时，报了一个很奇怪的错Websocket upgrade failed by [Connection timed out]

[zwl7]

具体错误信息是
[2023-03-08 11:29:07 $22941.0] WARNING check_worker_exit_status: worker#0[pid=22991] abnormal exit, status=255, signal=0

我的复现代码，我启动了一个ws服务端，然后再onworkerstart的事件里新建了一个协程去连接第三方的wss接口拿数据。
public function __construct()
{
$this->WebServer = new \Swoole\WebSocket\Server($this->ip, $this->port);
$this->WebServer->set(array(
'worker_num' => $this->workerNum, // 一般设置为服务器CPU数的1-4倍
'daemonize' => 1, // 是否为守护进程 1，0
'heartbeat_idle_time' => 90, // 客户端心跳时间1
'heartbeat_check_interval' => 45, // 每60秒遍历一次
'log_file' => DIR.'/swoole.log', // 日志文件信息1
'reload_async' => true, // 设置异步重启开关
'max_wait_time' => 5 // 设置 Worker 进程收到停止服务通知后最大等待时间
));

    // 绑定回调事件
    $this->WebServer->on('workerStart', array($this, 'onWorkerStart'));
    $this->WebServer->on('message', array($this, 'onMessage'));
    $this->WebServer->on('workerError', array($this, 'onWorkerError'));
    $this->WebServer->on('workerExit', array($this, 'onWorkerExit'));

    // 开启swoole服务， 程序回阻塞在这里
    $this->WebServer->start();
}

public function onWorkerStart(\Swoole\WebSocket\Server $server, int $workerId)
{

        go(function () {
            $sub       = [
                'sub' => "market.btcusdt.ticker"
            ];

            // 使用SaberGM(官方的链接webscoket客户端包)，链接火币的WebSocketUrl（wss://api.huobi.pro/ws）
            $websocket = SaberGM::websocket('wss://api.huobi.pro/ws');

            //订阅对应的行情
            $websocket->push(json_encode($sub));

            var_dump($websocket);
            while (true) {

                // 接收数据
                $recv_data = $websocket->recv(1);

                // 火币返回的数据默认经过了gzip压缩，需要解压
                $data = json_decode(gzdecode($recv_data->getData()), true);
                var_dump($data);
            }
        });

}

'wss://api.huobi.pro/ws'这个wss的域名我用在线工具(http://www.websocket-test.com/)可以连接通,但用saber连接会报错那个超时的错误，感觉不像是url的问题
