workerman作为wss客户端提示Sec-WebSocket-Accept not found

 
问题同：https://wenda.workerman.net/question/3379 ，但该哥们说找到是自己的问题了，我这边还是有问题，麻烦各位大佬帮忙看看问题所在.
 
在浏览器端可连接，原ws地址是：wss://ws.coincap.io/prices?assets=bitcoin,ethereum，ws://ws.coincap.io:443/prices?assets=bitcoin,ethereum，这种URL形式也试过的.

require_once __DIR__.'/vendor/autoload.php';
use Workerman\Connection\AsyncTcpConnection;
use Workerman\Worker;

$worker = new Worker('text://0.0.0.0:6161');

$worker->onWorkerStart = function() {
    // 以websocket协议连接远程websocket服务器
    /*$context = ;
    $con = new AsyncTcpConnection("ws://ws.coincap.io/prices?assets=bitcoin,ethereum", $context);*/
    /*$con = new AsyncTcpConnection("ws://ws.coincap.io/prices?assets=bitcoin,ethereum");
    $con->transport = 'sslv3';*/
    $con = new AsyncTcpConnection("ws://ws.coincap.io:443/prices?assets=bitcoin,ethereum");
    //$con->transport = 'ssl';
    // 注册连接上后的事件
    $con->onConnect = function($con){
        echo "connected\n";
    };
    $con->onWebSocketConnect = function($con, $http_buffer){
        echo $http_buffer;
    };
    // 远程websocket服务器发来消息时
    $con->onMessage = function($con, $data){
        echo "recv: $data\n";
    };
    // 连接上发生错误时，一般是连接远程websocket服务器失败错误
    $con->onError = function($con, $code, $msg){
        echo "error: $msg\n";
    };
    // 当连接远程websocket服务器的连接断开时
    $con->onClose = function($con){
        echo "connection closed\n";
        $con->reconnect(1);
    };
    // 设置好以上各种回调后，执行连接操作
    $con->connect();
};

Worker::runAll();
