ME MDM Does not download or accept MDM Server Name

ME MDM Does not download or accept MDM Server Name

Hi,
 
We have recently configured MDM for Desktop Central.
 
I can enrol a device either by email or auto enrolment fine without any problems. The app catalogue downloads onto the phone and information is passed back to the console with no problem.
 
When we push the ME MDM app via the App catalogue the app downloads but does not populate any of the server, port or email fields.
 
More importantly when I try to manually enter these details I get a warning stating "Error You are not authenticated to enroll your device. Contact your system administrator".
 
Please help
 
Regards
