Afaria Enrollment failed

Hello!

Help me to fix the problem. When I enroll Afaria client on the Android device I receive an error.

After entering the registration code, Afaria client hangs on the stage of device registration.

Long connecting and then it gives an error «Registration Failed»(in Russian Регистрация отменена)

Ports 443, 80, 8080 are opened.

We don’t use the relay server.

What is the cause that the enrollment process of the Android devices doesn’t pass? Where is my mistake?
