Getting Weasel in Destiny 2 over and over? If Bungie's servers are fine and it's just you, this is a network configuration problem. Destiny 2 is one of the most network-sensitive games out there.
Network-specific fixes:
- Port forward for Destiny 2 — this is the #1 network fix. Forward these ports to your PC's local IP: TCP 80, 443, 1935-1936, 3097, 3478-3480 and UDP 3074, 3097, 3478-3479
- Check your NAT type: you need Open or Moderate NAT. In Windows Settings search 'Xbox Networking' and run the test. If NAT is Strict, enable UPnP on your router or port forward
- If you have Double NAT (ISP modem + your router), put the ISP modem in bridge mode
- Switch DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8) — slow DNS causes authentication timeouts that trigger Weasel
- Disable IPv6 on your network adapter: Network Settings > Change Adapter Options > right-click > Properties > uncheck Internet Protocol Version
- Destiny 2 has known IPv6 issues
- Flush DNS and reset network: admin CMD > ipconfig /flushdns, then netsh winsock reset, restart PC
- If on wired and still getting Weasel, run 'pathping api.steampowered.com' (or Bungie's IPs) to find where packet loss occurs on the route
- Contact your ISP with the pathping results if packet loss is on their network
- As a last resort, try WTFast or ExitLag — they can route around bad ISP paths to Bungie
