使用[::]监听ipv6地址报错

在本地搭建的centos虚拟机上使用
new Worker("http://:$port");
的方式启动没有问题；
上传到阿里云服务器上后返回的错误信息如下：

Workerman start in DEBUG mode
PHP Warning: stream_socket_server(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /data/wwwroot/RocApiWorker/vendor/workerman/workerman/Worker.php on line 1445

PHP Fatal error: Uncaught Exception: php_network_getaddresses: getaddrinfo failed: Name or service not known in /data/wwwroot/RocApiWorker/vendor/workerman/workerman/Worker.php:1447

将监听方式改为
new Worker("http://0.0.0.0:$port");
后正常启动；
求原因或者思路~~
