Moodle cannot connect to Joomla

Can anyone help me with the last steps in connecting Moodle and Joomla.

My setup is:
Joomla version 3.9.2
sport-opleiding.nl

Moodle version 3.6.2
sport-opleiding.nl/educatie

Joomdle version 1.2.2
PHP Version 7.2.14

sport-opleiding.nl/index.php?option=com_...server&format=xmlrpc output = XML-RPC Error (1): Invalid token:

But the token in copy/pasted

Joomdle Web Services = Received empty response from Moodle

I searched various forums but nothing helped. My hosting company is WebOke.

Hi.

Do you get any other red items in system check, aside the web services empty response?

Every other is green checked. See screen below. I just update to Joomdle 1.2.3 in Joomla. But no extra green checks.

Ok, you can try this:
- Download www.joomdle.com/aux/joomdle_moodle_ws_client.php.zip and unzip
- Edit to add your site data
- Upload to your Joomla main folder and open it with the browser
- If Joomla and Moodle are on the same domain: If you get an empty reply above, upload file to a different server and open it with the browser. This way you can know if problem is only happening when the server connects to itself.

I placed the script and the outcome was twice:

Is this good or bad?

And some more screens

Hi.

I did some testing with your data (you should delete the pics, as they give confidential info) and it seems there is some problem with your Moodle.
If I add print_r ($response); to the file, after the file_get_contents call, I should get the raw XML, but instead I am seeing the entire Moodle page, with an "undefined" message that I have never seen before.
First thing I would try is chaing Moodle theme and testing again, to see if it is related.

I changed to the boost theme. But unfortunatly I got the same result.

Then problem must be caused by something else... although I don't know what, as I have never seen a similar error.
Try enabling debugging in Moodle to see if you can get more info, although I don't think it will help.

At this point, I would just try to debug Moodle web services code to try to find out what's happening, although that's not so easy.
