Resolution

As noted in the cmd.out file, the error is due to a communication failure between the agent and the WebUI.

The agent was not able to send the status back to Autosys-WebUI server.

Centralised agents upgrade feature requires communication between the Autosys WebUI server and the Agent.

Ensure that the agent host is reachable from the Autosys WebUI at the agent port number (agent_host:7520).

Also, ensure the agent is able to post messages to the WebUI server (8443).
