Hi there, Thanks for reaching out. Weasel errors are indicative of network issues. These can be caused by problems affecting your specific network hardware, packet loss, or greater issues affecting your ISP which are being passed on to you. Further, all of this is possible even if your connection seems fine at a glance. To that point, we recommend consulting our [url=https://help.bungie.net/hc/en-us/articles/360049496531-Network-Troubleshooting-Guide]Network Troubleshooting Guide[/url] to explore potential solutions. If that doesn't help, the next step would be checking our [url=https://help.bungie.net/hc/en-us/articles/360049024092-Optimizing-Connections-Improving-Latency-and-Packet-Loss]Optimizing Connections[/url] page. Following that, if issues still persist, we would recommend reaching out to your ISP for more hands-on assistance in troubleshooting your network setup.
