Hi there. Weasel errors can be triggered by a number of different issues all generally related to losing connectivity or being logged out of the game. There are some troubleshooting tips you can try [url=https://help.bungie.net/hc/en-us/articles/360048717852-Error-Code-WEASEL]found here[/url]. Weasel errors can also be triggered by you or someone else attempting to log into the game with your account on another device while you're playing. If it's not you doing that, then as a precaution we recommend following the [url=https://help.bungie.net/hc/en-us/articles/360048721292-Account-Security-Guide]Account Security Guide[/url] to help protect yourself from unauthorized access.
