Battlefield 1 Can't Go Online?

Hey there,

I have over 500 hours in BF1, and hadn't played it in a year or so, and got the urge to play the other day. I boot it up, and lo and behold, and told I can't connect to EA Online- the main menu has a "Go Online" button, which I hit, it says connecting, and then the main menu refreshes, still not connected. Interestingly, I am able to play all the other Battlefield games without issue- 3, 4, and V all boot up just fine, connect to EA Online, and let me play. Help!

I've done literally everything I can think of trying to fix this; here's a list:

Rebooted PC
Ran EA app as admin

Ran BF1 as admin

Made sure BF1 isn't being blocked by Windows Defender

Made sure file directory isn't being blocked by controlled folder access

Reinstalled game

Reinstalled EA app

Cleared EA app cache

Verified game files

Reset Windows network settings

Flushed DNS

Changed DNS

Forwarded relevant BF1 ports

Confirmed I don't have an account ban

Honestly I suspect I'm even forgetting some other things I've tried, but nothing has helped. I was able to chat with EA support twice, and they were not helpful, and now I see they've marked my cases as "Fixed" while obviously that isn't the case, despite assuring me that I'd be hearing back from them with escalated help. What's even more upsetting is now it seems the chat option I used in the first place to open the cases is gone?

Do I just have no recourse here? That seems insane, but then again, as far as I can tell, EA no longer has actual support?

Any ideas for things that might fix this and let me play BF1 again? Help!

Thanks!
