Might be worth keeping an eye on this thread if not already as it's the main one being updated by MS staff:

Sorry for the really late reply. It's not a problem with me. There's even a thread with an MS Employee who contacted Turn 10 and couldn't fix the problem.

Here are a few threads with the same issue:

There's even more. You have to get them to fix it. Or this will be a duplicate of the others.

I am using a Windows 10 PC and the other game I have tried is Forza Horizon and Forza Motorsport 7 which both are working via online MP. I am wondering that these are Microsoft developed games so these are bound to work online on their own platform.
