Login and Match Error Report for FC Mobile

Dear EA Support Team,

I’m writing to report an issue I encountered today while playing FC Mobile.

When I logged into the game, I tried to start a match, but it stayed in matchmaking for around two minutes and never entered the match. Later, I received an in-game mail stating that the match had ended in a loss, even though I never actually entered the game.

After noticing this, I checked my recent match history and confirmed that there was indeed a record corresponding to the same time — the one I never successfully entered.

I then tried uninstalling and reinstalling the game. However, when I attempted to log in again using my Apple ID, it showed a message saying “Login failed” followed by the error code:

0x80210000

Next, I tried logging in with my EA ID, but the login webpage wouldn’t even open and showed the following error message instead:

{"error":"invalid_request","error_description":"Invalid DOB in the mobile signature","code":100021}

Finally, I also tried logging in with Facebook, but it displayed another login failure message with a different code (unfortunately, I didn’t save that one).

Right now, I’m unable to access my account at all, and this issue is quite frustrating.

Please help me resolve this problem as soon as possible.

Thank you for your time and assistance.
