Hi there. Beaver errors 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. [quote]• These 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.
