Error Code: FLATWORM
BEAVER/FLATWORM/LEOPARD errors are caused by a failure to connect your console to another player’s console via the internet. This can be caused by connection quality issues (such as packet loss, ISP saturation, or general internet congestion). It can even be caused by certain WiFi setups, faulty in-home wiring, or other issues that require on-site support or expert investigation. However, they are most commonly caused by router or network configuration issues.
errors are most common when multiple consoles are connecting to the
internet through a single router. Some players have been able to work
around this issue by enabling UPnP on their router.
- Strict NATs tend to see these errors far more often than Open or Moderate NATs – opening your NAT can significantly reduce the frequency of these errors.
- Some types of connection quality issues (packet loss, etc) can trigger this family of errors. If you are using WiFi to play Destiny, we strongly recommend switching to a wired connection. For more: https://www.bungie.net/en/Help/Troubleshoot?oid=13604

We are also actively investigating the possibility that bugs are causing these errors to happen even on properly configured and well-functioning networks. This may be caused by general ISP outages. Follow @BungieHelp for additional information.
