Hello @kasuu2005 thank you for providing this screenshot.
We know some players have been affected by disconnection and certain 4-0 error codes recently, we are monitoring the frequency of each code that appears, and what platforms are affected.
Could you please get back to us and let us know what platform you play on, so we can pass this information on to the Siege team?
In the meantime, please follow all of the steps in our guide for whichever platform you experience this error code on, as these guides contain the most common fixes for connection issues and can help rule out certain things that may cause disconnections >
