When I go to Arena Multiplayer Beta it doesn’t allow me to select a playlist. It says “Error data center results. Please restart the Halo 5: Guardian Beta.”. It wouId only let me go on Slayer; Breakout and Stronghold didn’t work. Then I was on a chat with someone from the XBOX website and they told me to follow these steps. Go to Settings>Network>Advanced Settings> Alternate MAC Address> Clear. Now none of the playlists work. If anyone knows how to resolve this please let me know. Thank you!
