Configuration Options

Hi, I would appreciate a little help.

When trying to connect your plugin with a http://learninglocker.net/ instance
the LRS url should be like that?
http://mylearninglocker.org:8081/data/xAPI

Are the port number and “/data/xAPI” required, or is any other form required?

I have tried several variations, but the error is always
Warning: fopen(http://mylearninglocker.org:8081/data/xAPI/statements): failed to open stream: Connection timed out in /var/…/wp-content/plugins/wp-experience-api/includes/TinCanPHP/src/RemoteLRS.php on line 123
where line 123 is:
$fp = fopen($url, ‘rb’, false, $context);

Any idea why the connection timed out error?

Also, what is the latest version of your plugin?
The one from ww.wp.xz.cn v1.0.6, from 4 years ago?
Or the one from github.com v1.0.2, from 2 years ago?

Is it safe (albeit sad) to assume that it is no longer maintained?

Any help would be greatly appreciated.
Thanks in advance.
