Could not find ExecuteResult node in XML returned from Server Error

Hello,

I installed the Dynamics 365 Integration plugin in WordPress, and I’ve been following the AlexaCRM configuration instructions.

However, I’m getting this error message when I try to connect: ” Unable to connect to Dynamics 365:?Could not find ExecuteResult node in XML returned from Server. Check whether you selected the appropriate deployment type and that CRM URL and credentials are correct.”

The Debug Log is as follows:

wpcrm.NOTICE: Connecting to a new instance {"settings":{"authMode":"OnlineFederation","crmUrl":"https://pyrogenesis.crm3.dynamics.com/","ignoreSslErrors":false,"strictFederatedSTS":false}} []
crmtoolkit.ERROR: Caught exception during Execute request {"exception":"[object] (Exception(code: 0): Could not find ExecuteResult node in XML returned from Server at /var/web/site/public_html/wp-content/plugins/integration-dynamics/vendor/alexacrm/php-crm-toolkit/src/Client.php:1025)"} []

Can anyone please help me with this?
