Gateway::sendToClient(）消息发送不出去

use \GatewayWorker\Lib\Gateway;

Gateway::$registerAddress = '0.0.0.0:1233';

for ($i = 1;$i<100;$i++) {
Gateway::sendToClient("000000000b540000002c",json_encode(['ping' => 111111111111111111111111111111111111111111111111111111111111111111111111]));
}

print_r(Gateway::getClientSessionsByGroup("aa"));

消息发送不出去。抓包心跳消息却能实时推送, sendGroup和sendToClient全都发送不出去，
