Error in DMZ server : 20071 Event ID
The OpsMgr Connector connected to ..... , but the connection was closed immediately without authentication taking place. The most likely cause of this error is a failure to authenticate either this agent or the server . Check the event log on the server and on the agent for events which indicate a failure to authenticate.
Error in Mangement server :
The opsmgr connector negotiated the use of manual authentication with DMZ server but active directory is not available or no certificate installed
Any idea what would the issue
