FTD Stuck in "Discovery from the device is in progress"

[Bledian]

Hello all,

I have a problem while registering a new FTD 1010 to FMC.

The FTD is stuck in "Discovery from the device is in progress" for about 15 min and than FMC performs unregistration.

I have already registered 24 other same FTD 1010 with same version 6.4.0 to the same FMC, the problem

appears only with one FTD. 

Would appreciate any kind of help.
