An unexpected error happened: 28260048:

Today, I upgraded Moodle
Moodle 3.3.1+ (Build: 20170727)

Reinstalled the Joomdle Core (both moodle plugins) and the Joomla stuff.

The Joomla System Check reports this error:
An unexpected error happened: 28260048: Invalid response value detected | DEBUG INFO: joomdle_auth => Invalid response value detected: Invalid external api response: the value is "", the server was expecting "int" type | ERRORCODE: invalidresponse

joomla is 3.7.4 (most current)

I checked the raw logs
Moodle side says "its ok"
Joomla side reports the above error.
I'm still in PHP 5.6.3 for because another joomla plugin i use is not ready for 7.x yet.

Hi.

Check that Joomdle auth plugin is enabled in Moodle. I think this error indicates it is disabled.

That was the fix.
Everytime I update moodle, i have to reinstall.
I will update my process document to include checking this item as a potential challenge.
Pretty soon, I'll have all the checks in place to make sure that last check stays green. I know you have a complex plugin, so thank you for keeping it working. . .

Great to know that it is working now, thanks for letting us know.
