I start the first node without any error massage. when I start the second node, I get this error. I wonder why the second node can detect the name "StgApps15" (the server name of the first node) in its error massage? I think the server name of the first node is not resolvable ( the first node has more than one network interface). Could you tell me how to change the server name by configuration?
