Hi there, Thanks for reaching out. As megatron1984 mentioned, you will indeed need to try again, as leaving the dungeon for any reason, including being error coded in this way, unfortunately invalidates an attempt. Regarding Weasel errors, these are indicative of network issues, and 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. 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.
