Hi,
I have an issue of the connection between an installed AppAgent (Java) in Application Server (On-Premise, Linux CentOS), which is already mapped to Public IP, and SaaS Controller (License expires : 14/02/2024)
By the way I've already set up proxy on /etc/profile, and my Application Server be able to curl the SaaS Controller,
but the following errors still occur like there's another configures i need to set up more but I have no idea Y_Y :
[AD Thread Pool-Global0] WARN ConfigurationChannel - Could not connect to the controller/invalid response from controller, cannot get initialization information, controller host [SaaS domain], port[443]
[AD Thread Pool-Global0] ERROR NetVizAgentRequest - Fatal transport error while connecting to URL [http://127.0.0.1:3892/api/agentinfo?timestamp=0&agentType=APP_AGENT&agentVersion=2.4.0]: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:3892 [/127.0.0.1] failed: Connection refused (Connection refused)
[AD Thread Pool-Global1] WARN NetVizConfigurationChannel - NetViz-ConfigChannel-039 : NetViz configuration retrieval failed with reason [Connection back off limitation in effect: /controller/instance/null/netvizagentconfiguration]
Solved! Go to Solution.

Hi @Yatphiroon.Prempree ,
[AD Thread Pool-Global0] ERROR NetVizAgentRequest - Fatal transport error while connecting to URL [http://127.0.0.1:3892/api/agentinfo?timestamp=0&agentType=APP_AGENT&agentVersion=2.4.0]: org.apache.http.conn.HttpHostConnectException: Connect to 127.0.0.1:3892 [/127.0.0.1] failed: Connection refused (Connection refused)
Do you have network agent running? App agent appears to be attempting a connection with network agent. You can disable the following to stop these error messages if you don't have a network agent.
OR
You can ignore those errors as it should not have any impact.
Disable Socket Instrumentation
- In the Controller, click the gear icon in the top right and choose AppDynamics Agents > App Server Agents.
- Select the agent in the table and click Configure. The App Server Agent Configuration page appears.
- Select the application, tier, and node in the treeview (left).
- Select Use Custom Configuration and then click + (the "plus-sign" button) Create Agent Property.
- In the Edit Agent Property dialog box, specify:
- Name = socket-enabled
- Type = Boolean
- Value = false
