the agent was reported successfully until the following error happened
ِِERROR NetVizAgentRequest - Fatal transport error while connecting to URL [http://127.0.0.1:3892/api/agentinfo?timestamp=0&agentType=APP_AGENT&agentVersion=0.10.0]: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:3892 [/127.0.0.1] failed: Connection refused (Connection refused)

Hi
The error you see is related to Network visibility. By default the Java agent is trying to send data to the Network Visibility agent on the server that it's running on. If the network visibility agent is not installed/running, you will see this error. I believe in the latest release of the agent java agent this value is set to false by default, to not generate this error.
Technically this should not interfere with the Java agent itself and would just fill up the logs with unnecessary errors.
To stop this error from occurring you can set a agent node property to tell the java agent to not send data to the NetViz agent as its not installed and/or running. Or you can install the NetViz agent if you want to accept the data from the Java Agent.
Node Agent property below
name : socket-enabled
type : boolean
value : false
Save and apply to the agent.
Ciao

Thank you Mario for your reply.
So this is not the actual error that makes the agent not respond correctly to the controller
i found the following error in the log as well.
