Head over to Steam and click on Clear Download Cache from the Downloads sections present inside Steam Settings. Restart the PC after this step to enter a fresh session.

It is important to note that these are not official fixes and only a few methods that have worked for some individuals in the communitty.

Possible reasons

There are two potential reasons for this issue—unstable internet connection on the user side or heavy server load on the game’s side. An unstable connection can cause players to lose access to CS2’s official servers. This can result in the profile being logged out for a duration, disconnecting it from the ongoing match.

Server load is another possibility as it can cause issues like complete shutdown. It can also automatically disconnect certain players to regain stability. The hardware that supports these titles is built to cater to a limited number of accounts and host games at a time. This is why the devs usually set up safety protocols for such scenarios to help the server shed some load in case of such a scenario.

It is also possible that the game failed to boot some features that deal with the online connectivity of the user with the game server. This might result in a successful matchmaking process but fails when players need to be seeded into their respective teams for the match to begin.
