  • Disable firewalls on both the local computer and the agent computer.
  • If you do not want to disable firewalls, you can instead enable a firewall-aware connection. For more information on enabling a firewall-aware connection, see Running with a workbench behind a firewall.
  • On the local computer, check the properties of the location that represents the agent computer. This error can occur if the Deployment Root Directory is not specified correctly in the location that represents the agent computer.
  • Check the Error Log for further information on the error. To open the Error Log, click Window > Show View > Error Log.
  • Restart the Agent Controller.
  • Restart the application.

If the problem is not on an agent computer, check that the workbench computer has sufficient memory. To increase the available memory, either increase the workbench heap size or reduce the level and amount of execution history.
