There is a patch in the works which will include a possible fix for this issue, as well as more detailed error messages, to provide more information in case that doesn't help everyone with connection problems. There is no firm ETA yet on the patch, yet, just December.
We are continuing to work with Focus and Microsoft to investigate the problem, and there are other options being explored.
While I am glad this is being addressed..... December - really? Do you have any idea why this just appears to be an xbox one issue? Usually MS online works fine with games and PS network has the issues.
