Hi,

I’m experiencing a consistent disconnect issue with error 85009S.

The apparently knowm issue:

Game runs normally at high performance (100+ FPS)

After ~5–10 minutes → disconnect from server (85009S)

Troubleshooting already done:

Clean install of Windows 11

Reinstalled GPU drivers (latest Game Ready)

Verified game files (Steam)

Reinstalled EA Anti-Cheat (including manual repair)

Ran EA App as Administrator

Cleared EA App cache

Disabled background apps / overlays

Changed DNS (1.1.1.1 / 1.0.0.1)

Flushed DNS / reset network stack

Firewall checked (game + EA + Anti-Cheat allowed)

Tried different network (including hotspot)

Router restart

Clean boot (MSCONFIG)

No VPN / no connection modifiers

Game cost 60$ HELP
