With my new xbox I can download things but not play online.
Can someone help me please?
Do you have an Xbox Gold membership? You can only play online with this.
Yes, I have the ultimate game pass and live gold
What exactly is not working?
I can't join lobbys or join warzone, for example.
Simply everything that has to do with playing online.
Often this has something to do with the router. Try this: https://support.xbox.com/...-nat-error
Which router do you have?
My NAT type is already open
