    Hey everyone, 

    I hope you noticed an improvement, as our teams recently made changes that should reduce the frequency of this error, while we continue working on a full fix to be released in a future update.

    We are aware of an issue where some players would receive a Data Mismatch error when entering Clubs League matches, and have recently released a change to greatly decrease the likelihood of encountering this issue.

    The full fix for this issue is expected to be included in a future title update.

    Thank you for your patience with this and for all your reports here.

I’m experiencing matchmaking failures in FC 27 affecting both Clubs and Rush Tournament.

Clubs:
Our Club is unable to find/start a match. We get a message data mismatch/matchmaking failure right after match loads and returns is to the clubs Home Screen.  It finds the match but somehow when loading fails.

Rush Tournament:
The game successfully searches and reaches “Match Found”, but then immediately gives “Connection to opponent lost.”

Important: Normal Rush matchmaking works correctly. The problem appears to be specific to Rush Tournament.

Troubleshooting already attempted:

  • Fully restarted FC 27
  • Restarted PS5
  • Entered Ultimate Team and returned to The Grounds
  • Disabled cross-play
  • Changed regional matchmaking settings
  • Tried matchmaking with a different teammate as the party/search host

The same Rush Tournament failure occurred when my teammate hosted the search.

We have not yet tested whether my teammate can successfully enter a Rush Tournament match completely solo.

Please investigate whether there is currently an issue with FC 27 Clubs matchmaking and/or the Rush Tournament matchmaking/session initialization.

Teammates tried rush tournament without me and it failed for them as well.
