Cannot connect to background service


If you attempt to start the Code42 agent and it displays the message, "Code42 cannot connect to its background service", this article can help troubleshoot the issue. This error usually occurs because the Code42 service is not running.

However, if you see "Unable to connect, check your network" or "Can't connect to server", that indicates a network issue. Network issues occur when the Code42 agent cannot communicate with the Internet. To fix a network issue, check that there is no software that conflicts with the Code42 agent installed on your system and see Test your network connection to further troubleshoot the issue.

Under the hood

The Code42 agent consists of two parts:

  • Graphical user interface that the user interacts with
  • Code42 service that runs in the background

These two pieces communicate over a local network connection that is built into every device. When the Code42 agent starts, the graphical user interface and the Code42 service attempt to connect to each other. If they can't connect, the graphical user interface displays an error message.

To learn more about Code42 agent status messages, see Code42 agent status messages.
