Hey there! This error is typically seen with networking problems. Check out Bungie’s help guide (https://www.bungie.net/en/Help/Article/11783) on the topic: [quote] Bungie is actively tracking this general networking error. Your disconnect was reported the moment it occurred. This error can be due to packet loss or disconnections between your home network and Bungie (such as ISP saturation or general internet congestion). It can even be caused by certain WiFi setups, or mobile hotspots that may have experienced a blip or loss of connection. Before proceeding any further, we strongly recommend switching from WiFi to a wired connection, at least temporarily. This is an important first troubleshooting step to rule out WiFi signal strength/stability as a possible culprit. If you're experiencing an issue where you repeatedly hit this error and cannot log into Destiny, please attempt to force quit Destiny by completely closing the game and relaunching Destiny to get out of this state. If you continue to receive this error, please consider following the suggestions in our Network Troubleshooting Guide (https://www.bungie.net/en/Support/Troubleshoot?oid=12915) [/quote] Definitely try to force quit or hard reset. That tends to solve a lot of problems. Hopefully this helps!
I would personally try to verify your files if you are on steam. You could also try to unplug and replug your router to see if that alleviates some stress. These things have helped me in the past.
