Profile Manager Enrollment : "Invalid Profile"

Hi to all,

Hoping someone can help me with my problem in my Lion Server's Profile manager.

Im having an error once I enrolled clients iOS device through https://mydomain/mydevices saying "Invalid Profile"

Actually, its running perfectly for one year as an addressbook server to our companies 100+ iphone. This problem occurs

once I'd changed its expiring SSL certificate. The thing here is that Trust Profile and Configuration Profile push through without having any problem not just

the Device enrollment. I did not change any of my router nor any setting at all. As in only renewing the SSL cert.

Thanks for the help in advance.
