Network Objects missing in Network Atlas

since this morning, the network objects on our network maps turned into grey (unknown status)

they all got the right node ID but it seems that the "Network Atlas" couldn't find the objects.

in the Network Atlas program on the server, i can see all maps but no objects

i know that there was a vendor group taht conained all our network objects.

any idea what went wrong?

versions of all modules:

Orion Core 2012.1.1, IPAM 3.0, NCM 7.0.2, NPM 10.3.1, IVIM 1.3.0 © 1995-2012 All Rights Reserved
