Failed to host lobby in COD BO4

A lot of people have been reporting getting this one. There’s a bunch of stuff you could try, but none of it is guaranteed to succeed. It seems like a server issue, but you can try restarting the game, your console/PC, the network equipment you have (router, modem, etc). If you’re on PC, you could also try using a different DNS or running as an administrator. Make sure Windows is updated, and also try repairing the game through the client.

COD BO4 crashes, freezing, performance issues

There have been complaints about poor performance across all platforms. Sometimes they’re tied to a specific map, other times they’re global.

UI Error 21673
