Error: Joomdle version is different in Joomla and Moodle

Hi

I have this same error here

Joomla 4.4.1
Joomdle 2.2.3
Moodle 3.9.1
PHP Version 7.4.33

My situation might be a little bit different, I have an existing website which running on Joomla 3 and Moodle 3.9, then I install a Joomla 4 on the same hosting, but on different sub folder, and trying to reattached the existing Moodle without much settings changes except the Joomla URL and Joomdle token, which from my understanding here should override the old linkage to the new Joomla 4, it's much better since before I got the "Receive empty response from Moodle" error message

What is this authentication plugin here? I don't see one or perhaps the latest Joomdle version is discontinued? Please share me some tips to overcome this issue

Thank you..

If you get the version mismatch error, it means that you don't have the same Joomdle version in Joomla and Moodle.
Go to Moodle and check the Joomdle auth plugin version installed (an upgrade to current one if it is outdated)
