Client was kicked by Easy Anti-Cheat due to “corrupt or invalid backend message”

I am writing to request assistance regarding an issue where a client was automatically removed from the server by the anti-cheat system.

The logs indicate the following message:
“ActionReason: 2 - Details: Corrupt or invalid backend message”

Date/Time: 2025/06/02 11:54:26 (UTC+X)
Platform: [e.g. Windows / Steam / Epic Games Launcher]

We would like to better understand what may have caused this action and whether it is due to client misbehavior, corrupted data, or a possible false positive.

Please advise us on how to proceed, and let us know if you require additional logs or diagnostics from our side.

Thank you for your support.

Hey there @sing129! This error can stem from lots of things, but most of the time it comes from a network integrity issue of sorts on the player’s side. This can occur somewhat randomly extremely rarely on it’s own or if the data was corrupted in any way. It is possible the client was memory or packet tampering, but there’s no clear indicator of this.

Is this only a one time report or are there multiple across your users?
