Game Still Gives Error 216 and 201

Hi,

I’ve been dealing with Error 216 (and sometimes 201) in Star Wars Battlefront II for several weeks, and nothing I do gets the game to connect to multiplayer. I’ve tried every fix I could possibly find, including extreme measures beyond what EA Support usually suggests. I'm now asking for a real escalation because this seems like their fault and not mine. I've:

Cleared EA App, Origin, and related cache folders
Reinstalled the game four times, on two different SSDs
Tried both Steam and Epic versions of the game
Logged in with brand new EA accounts
Unlinked and re-linked EA accounts multiple times
Switched between one and two routers
Flushed DNS, reset Winsock, changed DNS providers
Manually opened/forwarded all EA-required ports
Reinstalled Steam, Epic, and EA App from scratch
Used the old Origin client to bypass EA App
Fully disabled antivirus/firewall + manually allowed EA ports
Created new Windows user profile
Synced PC clock and verified region matches
Rebooted router, switched networks, and even used a mobile hotspot
Tried the Arcade → Multiplayer workaround
Got DDoS’d after following EA’s advice
Temporarily blocked my own IP to force handshake resets
Tried launching off of friends
Had the poor support people do some nonsense on their end that changed nothing
Installing directly from the EA app
Manually connecting to BF2 ports via steam and epic launch options
Asked a network engineer from a competitor to troubleshoot on my end
And countless others I can't even recall.

I’ve played countless other multiplayer games (on Steam, Epic, Battle.net, etc.) with zero issues. This only affects Battlefront II through EA’s infrastructure. It doesn’t matter what platform, what network, or what account I use, something is broken with their servers.

This issue is not fixable through local troubleshooting. Please don’t give me another copy-paste guide. I need real help from someone who understands EA’s backend. I’ve exhausted every option on my side. Thank you.
