EDITOR'S NOTE

This guide uses confirmed official information. Recommendations are practical starting points; live balance and availability should be checked in the game.

01

Check official status

Activision Support provides service and connectivity updates. Platform network pages can show separate issues affecting sign in or multiplayer matchmaking.

02

If services are operating

Restart the game and platform client, check for pending updates, then test a wired connection if available. Avoid reinstalling before confirming whether the issue is widespread.

03

Keep evidence

Write down the error code, time, platform and whether the issue affects sign in, matchmaking or a single playlist. That makes support guidance more useful.
