STEAM - Connection Failed Error 1:86001S:66003S:468882297O:0B - EA Backend Issue
I cannot connect to Battlefield 6 servers via Steam. Getting consistent error:
Connection Failed - Error Code: 1:86001S:66003S:468882297O:0B
Platform: Steam (purchased on Steam)
EA Account: Verified linked to Steam at ea.com/account/connections
Troubleshooting Steps Already Completed:
- Verified game files integrity on Steam (100% validated)
- Cleared EA App cache via Help > App Recovery
- Ran EAAntiCheat.GameServiceLauncher.exe as administrator
- Changed DNS to Google DNS (8.8.8.8 / 8.8.4.4)
- Restarted router (full power cycle)
- Logged out and back into EA Account
- Reinstalled EA App completely
- Verified Secure Boot and TPM 2.0 enabled
Result: Error persists after all standard fixes.
Additional Information:
Based on forum research, this appears to be an EA backend authentication issue affecting multiple Steam players. The error structure 1:86001S:66003S suggests account ID mismatch that cannot be resolved client-side.
Multiple threads confirm this same error:

Request: This requires EA backend team intervention. Can a community manager or EA staff member escalate this to the authentication team? This is blocking gameplay entirely since launch.
