Why won’t black ops 3 connect to online services?

Hello Wesley, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

I’m sorry to hear you’re having some trouble when trying to play Black Ops 3 on your console. Let’s try to sort this out.

However, before that, I would like to ask some questions:

Are you playing the game on Xbox One or Series X|S?
Is this behavior occurring with more games, or is just Black Ops 3?
Please describe briefly what procedures you tried to fix this prior to your post creation. That way, I can suggest other possible solutions.

Meanwhile, I would like to confirm if you tried this possible solution as well:

My black ops 3 online service is no able to connect plz help

On black ops 3 i get the ABC error. On modern warfare it just says connection failed, or cant connect to online services

I have issues with black ops 1, skate 3, modern warfare 3, and it doesn’t show a code when I test NAT type it says” it looks like your NAT type is open right now” I also don’t really know when this started happening. I can not play online with friends is what I’m trying to let you know I can only play offline. For example when I want to play zombies it won’t connect me but I can play solo. For skate 3 it won’t connect me to Ea nation.

I am unable to play any of my Xbox One games such as Black Ops 4, it wont let me connect to the online service. Help!
