Xboxlive is having an overload of players between Halo 4 and COD:BO2. Its going to be an issue on and off for a while and even worse when christmas comes. Its happening with other games too. Its xboxlive.

Hey Jennifer,

Welcome to the Xbox Forum!

There aren't currently any issues or server maintenance affecting online multiplayer in Black Ops Cold War:

Activision online service status

Xbox Live Status

What console is your daughter using - Xbox One or Series X|S?

What's your NAT type - ‘Open’, ‘Moderate’ or ‘Strict’? Ideally, you want this to be ‘open’ to play online.

From what I've found on this error, changing the DNS server can help. Unfortunately, there doesn't seem to be any known solutions to this error, only temporary workarounds.

If you're connected to a wireless network, you might want to try using a wired connection to see if this helps or try another network, a mobile hotspot maybe?

There's also a Reddit thread on this here.

If this issue persists contact Activision support or reach out to them via Twitter @ATVIAssist

Hope this helps!

Just an update to let all know that I fired Halo 4 up the other day and all was fine again.

Looks like its just one of those things that we will have to deal with at this busy gaming time of year.

It seems to be a very intermittant issue and it is the first time I have experienced it. No split screen was involved but frustrating either way round.
