FC 27 players report disconnection errors during the Hall of FUT Unleashed League objective, which grants a free 86-rated Hero. The disconnects typically occur immediately after matches begin, voiding results. EA Sports has not yet fixed the bug, which also appeared during the previous Ultimate Scream objective.
To work around the issue, players should create a new squad with no custom tactics enabled. Starting a match with this squad may prevent disconnections, though opponents who haven't applied the same fix could still trigger a disconnect.
The HOF Unleashed League requires players to complete a series of win objectives ranging from one win to fourteen wins. A bonus objective set also demands a specific number of goals scored. The disconnection bug makes progress impossible when it triggers, since match results become void.
