I have been getting error code beaver when going to the tower or trying to play any pvp all season. I have tried everything I can related to the help article. The bizarre thing is there are 3 of us that play from here and I am the only one having the issue. If it really is some sort of NAT issue, that makes no sense then.
The BEAVER error occurs when players experience connection quality issues (such as packet loss, ISP saturation, or general internet congestion). You may want to review our BEAVER article at http://help.bungie.net for more information.
You may want to review our guide on [url=https://www.bungie.net/en/Help/Troubleshoot?oid=13603]improving latency and packet loss[/url] to see if that might help.
