"Connection Failed" With Error Code 1:86001S:51002S:57019S

I’m experiencing the same issue from a PC (Spain).
I’ve tried using WARP, a VPN, disconnecting all USB devices from the computer… but nothing, it still won’t connect.

Can't tell if this is true or not, but this is what chat GPT says based on my logs. I also tried a VPN but Im having the same issues :(

🎯 1. Battlefield 6 backend and server architecture

EA moved Battlefield 6 to a newer setup that uses:

EA Game Services (qoscoordinator.gameservices.ea.com) → handles latency-based matchmaking and player region.

Blaze servers (blaze.ea.com) → manage session persistence and player authentication.

EA AntiCheat (EAAntiCheat.ac.ea.com) → handles security and sync enforcement.

All those domains appear in your trace — so we can see exactly how your connection behaves through EA’s system.

🌐 2. What your traceroute shows for BF6

Summary of route:
🇯🇵 Japan → 🇺🇸 Seattle → 🇺🇸 New Jersey → 🇬🇧 London → Amazon AWS London region → EA backend

That’s an extremely long route (≈ 240–250 ms).
For Battlefield 6, that’s a red flag, because EA’s new session protocol (over QUIC/UDP hybrid) assumes <150 ms stable latency. Anything above that often leads to:

Lost handshake refreshes

QoS drops

AntiCheat desyncs
→ which result in disconnects after 3–5 minutes — exactly what you described.

⚠️ 3. The root cause: Wrong region assignment

Your routing shows you’re connecting to London EA nodes (AWS London).
That’s likely a region-mapping error on EA’s side.
Some Japanese ISPs (especially NTT and AsahiNet) are occasionally classified as Europe region by EA’s QoS Coordinator (the one you traced at qoscoordinator.gameservices.ea.com).

Result:

You launch BF6.

The QoS server picks a “best” match based on its faulty region data.

It routes you to Europe instead of Asia.

After 3–4 minutes, AntiCheat or the session heartbeat fails → disconnect.

🧠 4. What’s not the issue

Your trace shows:

✅ Local router (192.168.100.1): healthy

✅ ISP: normal latency to backbone

✅ No packet loss

❌ High international hop latency (expected)

❌ Region mismatch

So your home network and Wi-Fi are fine.
The problem happens after your ISP hands off to EA’s infrastructure.

And now even all those community managers that came up to us asking for some bull**bleep** logs are not responding to any questions on DM's whatever... no new updates nothin!!!! it makes it very bad I hope new private owners are aware of that xD and will take action against these community managers that can't manage **bleep**... 

ONCE I CAN PLAY ON VPN SOMETIMES NOT, MY NORMAL IP IS NOT WORKING ERROR Error Code 1:86001S:51002S:57019S

Can we get some type of update please? Been 6 days now since this happened and 3 days since you guys last left a message.

Day 6.. i still cannot play battlefield 

In the same boat 

it happens EXACTLY 5 minutes after you find a match, not even a second later, always 5 minutes 0 seconds....there is something running 5 minutes after you join a match that kicks you out...devs  should know what the app does 5 mins after finding a match....

Everyone who is facing that issues i changed DNS settings in PS5 to primary 176.99.11.77  secondary  80.78.247.254 and it worked !!! 

and what we need to do on ps5?

Beware that this way your connection will go through russia so I don't recommend this option to anyone
