Check the Control Manager IP address and port.
Run https://{TMCM_Server}:{Port}/ControlManager/ClientCGI/cgiDelegate.dll to verify the connection between OfficeScan and Control Manager.
If the connection is successful, the "8-15205" page displays. If the connection fails, the "Page not found" page displays.
Check the error code in the Product.ini file in the \OfficeScan\PCCSRV\CmAgent folder.

Solutions:
Stop the MCP agent service.
Change the agent build number in the Agent.ini file in the \OfficeScan\PCCSRV\CmAgent folder.
