Persistent Error 1:85009S since early February - Need assistance

Hi everyone,

I’m reaching out because I’ve been unable to play Battlefield since the beginning of February due to the Error Code: 1:85009S.I have tried multiple troubleshooting steps found online, but nothing seems to work. Here is a quick summary of my situation:

Duration: The issue started in early February 2026 and has been persistent ever since.

when it happens: strarting game

Steps already taken: 

Cleared EA App cache.

Verified integrity of game files.

Flushed DNS and reset network settings.

Disabled all overlays (EA, Steam, Discord).

Added the game to Firewall/Antivirus exceptions.

Despite all of the above, the error persists. It seems like a synchronization or server-side handshake issue, but I’m running out of ideas on how to fix it on my end.

Has anyone else dealt with this for such a long period? Is there a specific port forwarding or account-side fix that I might have missed?

Any help would be greatly appreciated!
