Users can experience NAT Type 3 or NAT Type D error codes while trying to host online games on the campus network. This is commonly found with gaming consoles such as the PlayStation 4 or Nintendo Switch.
If you are experiencing one of these errors and are still able to join other online sessions, it is recommended to have an external user outside of the campus network host the session. This doesn't work in all scenarios. If you are not able to access any matchmaking activities, please fill out the form at the link below for further assistance.
