PHRETS Works Locally But Times Out On Web Server

Question

I installed PHRETS with Composer and have been able to print information using CMD terminal and following the docs. I tried uploading all the files to my web server, but the page times out.

My error log shows the following:

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:

#4 /public_html/phrets/vendor/guzzlehttp/ringphp/src/Client/Middlewa in /public_html/phrets/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php on line 49

How can I get it working on the web server? Below is my configuration.

$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);

Turns out, I just needed to enable port 6103 on the server.
