3cxpbx and Vtiger CRM integration issue.

[MOS-Admin]

Hello

We are trying to integrate the PBX with our Vtiger CRM But at server side Integration we are getting the error:

Started scenario with empty id
Started Auth
Request text: http://<Domain>/webservice.php?operation=getchallenge&username=admin
System.Exception: Server returned a non successful status code - HTTPStatusCode=InternalServerError - Reason=Internal Server Error - Content=


Any suggestion is appreciated.

Thanks,
