2 Match No Longer Exists — Company Of Heroes

This error has plagued the Relic-developed RTS since its 2013 release. It appears just as you load into a 3v3 or 4v4, or when you try to rejoin a game after a disconnect. You stare at the loading screen, anticipation building, only to be kicked back to the main menu.

In this deep dive, we will explain exactly what "Match no longer exists" means, the technical reasons behind it, the difference between this error and a ban, and the step-by-step solutions to minimize its occurrence. In the simplest terms, the error is a communication breakdown between your game client and Relic's matchmaking servers (CoH2.org).

A ban produces a very specific message: "You have been permanently banned from Company of Heroes 2 Online services." Or a simple "Authorization Failed."

Why does this happen? Is it your fault? Is the server dead? Is the community gaslighting you?

When you queue for a match, the server reserves a "session slot" for you. By the time your computer finishes loading the map assets (trees, snow, destroyed buildings), the server checks to see if that session is still active. If the server responds with "Session ID not found," you get the error.
