Black ops 4 Xbox One and no error code

Hey there Spartan thanks for the clarity.

We apologize for the inconvenience this has caused but rest assured we are here to help, first things first we suggest
clearing out the consoles caches since when they get full might cause this type of errors.

How to clear Game Cache on the Xbox One:

Settings

System

Storage

Clear Local Saved Games

Yes and Restart




To clear the Network Card Cache (alternate MAC address)

Settings

Network

Network Settings

Advanced settings

Alternate MAC Address

Clear and restart

IF THE CONSOLE IS CONNECTED TO THE INTERNETno
progress or purchase data will be lost, what we accomplish by doing these steps would be to resync the profile to the cloud getting rid of any corruption as a byproduct.

Give these steps a shot and let us know if we can further assist in this or any other issues or inquiries!!

using 2 xbox ones in the same house requires a router that supports "multiple consoles" , if your using a router from your isp , I doubt that it does ...

I am getting exactly the same thing. I can join any other game but can't join the other Xbox one in the house. Both ant types are open.
