Error 10000 - Unable to join or rejoin a league

Hey everyone! 
I just wanted to check if any of you have recently changed leagues within a short period. This error can also happen if the group has already reached its maximum size. Please also keep in mind that you’ll need to wait a bit before switching leagues again, as there’s a cooldown period between changes. 

There has been a bug report with me and my friend about when trying to join a league we keep getting error code 1000 or 10000 how do we resolve this and we restarted our devices multiple times yet it still didn’t work and we have good internet connection so Ea pls fix this

I have opened a new account and now trying to join a league. Whenever I click join it kicks me out of the game and shows error 1000. It should be fixed as fast as possible.

I don’t know what to do could you fix my problem. [removed] Is my account uid. If you need anymore information please contact me 

Dear EA Sports FC Mobile Support Team,

I am writing this to report a persistent technical issue I am experiencing while playing FC Mobile.

Issue Description:

Every time I attempt to join or register for a new league after leaving a previous one, an error message appears. The error message reads: "UNKNOWN ERROR[10000]".

Important Details:

My UID: [removed]

Device: Realme 7

Platform: Android

Approximate time when issue started: November 16, 2025 (1 day ago)

Server: Indonesia

Game Version: 26.1.01 (Latest Version)

Evidence (Attached): I have attached a screenshot of the error message that appears.

Steps I Have Taken:

I have attempted all basic and advanced troubleshooting steps suggested in the community forums, but the issue has persisted for over a day:

1. Ensured a stable network connection (using both Wi-Fi and cellular data, both are fine for solo play).

2. Restarted the application and device multiple times.

3. Cleared the app cache and data (clear data) and reinstalled the game.

4. Paused logging in or attempting to join a league for over 24 hours.

5. Changed the region/area settings on my device.

Desired Outcome:

If my account has indeed been flagged for a violation and received a restriction, I sincerely apologize. I promise that I will not repeat it again. I suspect this may be a temporary account restriction that has not lifted automatically or a specific server authentication issue. I kindly request assistance from the technical team to review my account status and restore normal. Thank you for your time and assistance.

I see you merged the threads. I got one more to add on our own. Sanyosa and I are still seeing applications we cannot reject.

I’ve merged some of your individual posts into this single thread. I’m also trying to confirm whether you’ve all recently changed leagues within a short period or are trying to join a group that has already reached its maximum size.
