What is Error Code 2901 in Black Ops 6?

Error Code 2901 usually pops up when playing through a Game Pass subscription on a shared account.

It can also come up if you’re playing on the original Game Pass account that isn’t set as the home Xbox. Additionally, ongoing server maintenance by Activision can also trigger this error.

How to fix Error Code 2901 “Lobby not found”

Before delving into fixes, head over to the official server status page. If maintenance is underway, the error likely stems from that. If the problem is caused by the server, wait for the maintenance to end, and you should be good to go.

We also recommend restarting your game, router/modem, and your device just to check if it fixes the problem. If the simple tricks don’t work, here are some other methods:
