Comcast and Microsoft are aware of a software issue affecting the ability of Xbox One users to play some games online. This issue is only observed when the Xbox One is connected to a network via WiFi and when that network also has an IPv6 address. In those conditions online gameplay for some titles may not work.
To immediately solve this issue, we recommend that customers connect their Xbox One using an Ethernet cable instead of WiFi. Comcast and Microsoft say they are working together to further diagnose the issue and we anticipate that Microsoft will release a software update after the holidays that will resolve this issue.
