ModernPos : initialize data failed on first logon

Hi, 

After turn on the application at the first login, a quick message appears:

A problem occurred with the encryption device. Call your system administrator

Notes: 

1. The device has been activated
2. The realtime work on Retail Pos (fat client)
3. The modernpos App work correctly (activate and logon) with CU8 demo contoso VM

Explain :

I can activate modernpos on vm demo contoso , and then log in.

If I run the same operation on my own server retail environment , I also manage to activate modernpos , but I can not initialize the data . When I look in Fiddler , the queries stop at GetButtonGrids while in demo contoso environment , it continues with Shifts / GetByStatus and Shifts ( ShiftId = ' 1', TerminalId = ' HOUSTON -3') / Resume

I try to initialize the data parameter in retail but the problem is still present.
