Hello,
I'm already in contact with probosciger, however, I think it is important for all of you, that Windows Server 2008 R2 is not supported anymore by GRAPHISOFT.
Main component of BIMcloud Manager is not supporting this old version of Windows Server, so several different issues can be experienced.
We recommend you to check our hardware recommendations here:
