AD Connect - Staging-error

Hi

I have two AD connect servers running on windows 2012 r2 AD connect v1.1.119.0 (One in staged mode). I decided to migrate them to new servers. So I can have a newer OS and upgrade AD Connect to the latest version. 1.5.45.0

I installed AD Connect on the new servers and enabled Stage mode on both new servers. When I run a Full Import (either AD or AAD), I get 5000 errors saying Staging-error and then the job stops. There is an event 6301 for every error:

The server encountered an unexpected error in the synchronization engine:

"BAIL: MMS(5576): ..\sql.cpp(7536): 0x80004005 (Unspecified error)
BAIL: MMS(5576): x:\bt\1130526\repo\src\dev\sync\server\sqlstore\rcvtvp.h(158): 0x80004005 (Unspecified error)

BAIL: MMS(5576): ..\syncstage.cpp(414): 0x80004005 (Unspecified error)
Azure AD Sync 1.5.45.0"

Anyone can help me? I checked AV, FW and we found nothing. The funny thing is that both new AD Connect servers throw errors on almost the same objects.

The BD is local, just a normal installation.
