I have XBox Gamepass Ultimate, but for some reason I can’t play CoD Black Ops online...

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Yes, you should be able to play the game. First, please check if it's showing as active on your end by following the steps below:

Press the Xbox button on your controller to open the guide, and then select System > Settings > Account > Subscriptions.

Once confirmed, we may need to reset the console since you have already removed and re-added the account. Don't worry because as long as you're connected to Xbox Live your saved progress, games, will not be deleted. It will remove all of your accounts but you can add all of them later on.

Press the Xbox button to open the guide.

Select Profile & system > Settings > System > Console info.

Select Reset console.

Reset and keep my games & apps.

I have been playing Rainbow Six Siege and Call of Duty Black OPS 3. For some reason, COD say my NAT type is strict but the Xbox and Siege both say its open...

I picked up black ops 2 last sunday at a car boot sale for 50p,it the first time in a long time that i have played a cod game.

I wouldn`t dream of playing it online, for any reason.

I'm sorry, but Xbox Live Gold is not being shut down. It is still an active service that allows you to play Black Ops 2 multiplayer online. However, if you are referring to the Xbox 360 servers being shut down, it is possible that online multiplayer for Black Ops 2 on Xbox 360 may no longer be available. I recommend checking with the game's developer or publisher for more information on the availability of online multiplayer for Black Ops 2 on Xbox 360.

Xbox live gold.is being converted to gamepass core at no extra cost vs what you are paying for gold currently or you can opt for ultimate

I still have it; just don't see any reason to play it. It's CoD Black Ops in Third Person really.
