Solution 1: Reload the Game
Head back to the main menu, then reload multiplayer mode. This often does the trick. If it still shows the error, try restarting the game entirely.
Solution 2: Restart Your Device
PC Users: Fully restart your computer, then relaunch Black Ops 6.
Console Players (Xbox/PlayStation): Power down your console and turn it back on. Then, load the game again.
Solution 3: Check Your Internet Connection
Make sure your internet connection is stable. If there’s a hiccup in the network, it can cause server errors. Restart your WiFi router or modem to clear out any temporary issues. You could also try connecting through your mobile hotspot for a quick check.
