[SECURITY VULNERABILITY] - Connecting to online services UNKNOWN ERROR
I've been aggressively trying to tackle this issue for the past few days spending close to 10-hours in various streams of EA tech support channels, and I think I'm getting close to finding the cause....
Lucked out with a support tech that would actually action something (instead of just deferring to unhelpful documentation) and have found a workaround that has rectified the authentication loop error [1:86001S:51009S:11468332130:1073807360Q].
What I recommend doing to rectify the issue quickly, without waiting for EA to pull their finger out.
CONFIRMED WORK AROUND PROCESS:
- Download your EA profile data
- This is required because you'll need to identify which 'Persona' or EA ID to preserve
- Identify the EA ID which was used when you first played Battlefield 6
- I had a friend sit on the menu and watch as I launched the game through steam - the EA ID popped up saying "### is Online"
- THIS IS THE ID YOU NEED TO PRESERVE TO KEEP YOUR PROGRESS
- Get a coffee, and start the long painful process of cycling through EA support techs until you find one willing to delete old EA ID's
- Most will say they cant - just move on. Some of them CAN!
- Delete ALL EA ID's except the one you identified in step 2
- This will align EA's backend authentication systems with the BF 6 authentication systems and you should be home free
NOTE: EA games which may be using alternate EA ID's/Persona's will lose their progress - proceed at your own discretion
- Download your EA profile data
