Hello everyone,

I've trouble with the Installation of the SQL-Node for my 
SQL-Server-Cluster.
I'm a bit stuck and would appreciate any help =)

Somehow its not possible to keep the connection between SQL-Node and 
Management-Server, although the systems are in the same local network, 
no firewall between them or installed on them.

Management-Server Log:
