Failed to create meetings in parallel in Adobe Connect 9.5.3

Hi there,

We used to be able to create meetings in parallel via a Moodle Plugin by calling the web service in Adobe Connect 9.4.2 using PHP curl_multi_exec() function, but after upgrading to Adobe Connect 9.5.3 this function is broken. And we are getting the following error messages:

The same code is still working with Adobe Connect version 9.4.2, so we are wondering:

Is there any change in the Adobe Connect web service?

Is this a known defect?

Dose anyone have similar issues?

Any help would be appreciated!

Best Regards,
