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

In the same boat 

Day 6.. i still cannot play battlefield 

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.

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'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.

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.

Day 6. 

This issue is still a thing.

I tried all the solutions listed on the internet, nothing helps.

Adding myself to the list of people who cannot play this game because of this bug despite trying pretty much every troubleshooting step. For some reason removing my USB keyboard will sometimes allow me to get past the bug (????) but once I plug it back in I'll inevitably lose connection and be kicked out of the game again. Weirdly the few games I was able to match into were horrifically laggy. Given that this bug causes me to lose internet connection in other apps and crashes Cloudflare WARP when I try to use it to bypass the bug I can only assume that there are some absolute shenanigans going on with this games networking that need to be ironed out by EA. Definitely one of the most frustrating bugs given it seems to only affect a specific subset of people for truly unknowable reasons.

Haven't been able to play since launch and the site won't let me create a support ticket. I don't know what to do at this point now that I am passed the point of being able to ask for a refund. Please fix this EA, this is crazy.

For me it worked
