Received empty response from Moodle (Joomdle 2.2.3)

Hi

I saw this kind of question were quite popular in here, but I still can't find the working solution up until now

I'm using the Joomdle 2.2.3 + Joomla 4.4.1 and Moodle 4.1.7 with PHP 8.0, perhaps since the new structural change recently

In the beginning, I thought it might be the issue with my XMLRPC extension module but it was not the case since I learned that the new version of Moodle, starting from 4.1 has been freed from the dependencies - If I understand them correctly here

docs.moodle.org/401/en/Upgrading#XMLRPC

Based on the images attached, what could be gone wrong in my installation here?

Appreciate your valuable advise here

Regards

Hi.

When you get an empty response, it means that when Joomla tries to connect to Moodle web services, it gets an empty response.
This could be caused, for example, by some security measure in the server disallowing access.

Make sure you don't have a trailing slash in Moodle URL in Joomdle config in Joomla.
