# Online Debriefing Client

With Tacview, online debriefings can be performed during which all participants open the same `ACMI` file and the debriefing host can control that `ACMI` file throughout the debriefing.

The host and the client(s) must open the same `ACMI` file in Tacview’s 3D view (or their respective `ACMI` files recorded from the same session). Tacview will not transfer any terrain, static objects or media files, so ensure that the clients have access to these files before beginning the debriefing.

To be a client of an online debriefing, Tacview Standard is required. To [host an online debriefing](/tacview/features/tacview-advanced/online-debriefing-host.md), or to be given control, Tacview Advanced is required.

### Client Instructions

If connection fails, double-check the host IP address and confirm with the host that the port is open or redirected, and ensure the password (if applicable) matches the host's password.

To leave a debriefing, go to `Record` → `Online Debriefing` and click the `Leave` button in the connection window:
