Thank you for contacting EA help.
I am sending you this email in reference to our chat session regarding connectivity issue with the demo NHL 20.
I am glad I was able to help you with the game issues by sharing the relevant troubleshooting steps to sort it out in a follow up email.
Please follow these steps to resolve the issue-

1. Clearing the cache/Power cycling
While the console is on, press and hold the console’s Xbox button for 5 seconds.
The console will power down.
Unplug the power cord.
Wait 30 seconds.
Plug the power cord back in then turn the console back on by touching the Xbox button
Note: If your console is set to the Instant On power state, the above steps will shut the console completely off and will not enable Instant On or the ability to turn on your console by saying ‘Xbox On’ until it reboots.
2. Clearing persistent storage
From the Home Screen, using the controller scroll left to the navigation pane.
Scroll down to Settings Icon.
In the Settings menu scroll down to Disc & Blu-ray.
Select Blu-ray.
Select Persistent Storage and confirm your selection.
3. Alternate MAC Address
From the Home Screen, using the controller scroll left to the navigation pane.
Scroll down to Settings Icon.
In the Setting menu scroll down to Network and select Network Settings.

Select Clear.
Shut down the console.
Disconnect the power cord from the back of the Xbox One and wait two minutes.
Once the two minutes have passed, plug the power back in and wait for the power bricks light to go from White to Orange.
Once the power brick has the Orange light start the console and try the game again.
