Hi there, @russ83.

Try the steps below for your console - 

Xbox:
1. Close the game -> Go to the Xbox settings -> Network settings -> Advanced Settings -> Alternate MAC Address -> Clear.
2. Set your DNS manually to primary 1.1.1.1. and secondary to 1.0.0.1. in the Settings > Network > Advanced settings > DNS settings.

PS4:
1. Go to the PS4 Settings > Account Management, and select Restore Licenses. Click OK when done.
2. Go to the internet settings -> network -> set up internet connection -> Wifi/LAN (depending which he uses) -> custom on the Playstation and fill in primary 1.1.1.1. and 1.0.0.1. as secondary.

Let me know if this helps or not. Thanks!
