PHRETS在本地工作，但在Web服务器上超时

Question

我在Composer中安装了PHRETS，并且能够使用CMD终端打印信息并跟踪文档。我试着把所有文件上传到我的web服务器，但是页面超时了。

我的错误日志显示如下：

PHP Fatal error:  Uncaught exception 'GuzzleHttp\Ring\Exception\ConnectException' with message 'cURL error 7: Failed to connect to rets-rald.realtyserver.com port 6103: Connection timed out' in /public_html/phrets/vendor/guzzlehttp/ringphp/src/Client/CurlFactory.php:126
Stack trace:

我怎样才能让它在web服务器上工作？下面是我的配置。

$config = new \PHRETS\Configuration;
$config->setLoginUrl('http://rets-rald.realtyserver.com:6103/saskatchewan/rets/login');
$config->setUsername('username');
$config->setPassword('password');
$config->setRetsVersion('1.5');
$config->setUserAgent('PHRETS/2.0');
$config->setHttpAuthenticationMethod('digest');
$config->setOption('use_post_method', false);
$config->setOption('disable_follow_location', false);

Answer 1

结果，我只需要在服务器上启用端口6103。
