Community ManagerYou need a PC for the test. It can't be run on Xbox. That's unfortunate as it would really help find out why this is happening. Something else you can try is using alternate DNS servers. From the Xbox One home screen, go to Settings > Network > Advanced settings > DNS settings > Manual. (If Settings doesn't appear on the home screen, select My Games & Apps, then Settings). From there, enter the Primary DNS as "208.67.222.222" and the Secondary DNS as "208.67.220.220". If that doesn't help, try using the google DNS servers which are: primary alt number 8.8.8.8 - secondary alt number 8.8.4.4. Let me know if that makes a difference or not.
Hopefully it works better
Ive been on the google one for a while and my connection was trash
