Server Cannot Process Request Fix
Some players are reporting that they are getting the following error while trying to play Madden NFL 21.

“Our servers cannot process your request at this time. Please try again later”

This issue is being experienced by Xbone and PlayStation 4 players while trying to access Madden 21 Ultimate team. To fix the “Server Cannot Process Request” error, long-in to your EA account on PC > Settings > deny the access to the Xbox One account.

When players open the EA play app on the console, it’ll ask to connect the account. Select “Yes” and players will get to the main menu and will be able to access the Ultimate Team and the error will be fixed.
