EA Javelin "Security Violation / Error #95"

Subject: Apex Legends (Steam, AppID 1172470) — EA Javelin "Security Violation / Error #95" since EAC→Javelin transition; direct connections (PPPoE behind CGNAT and mobile hotspot) both fail, only overseas proxy launches then silently crashes

Network environment (key info):

• Connection: PPPoE dial-up (ONT in bridge mode, router dials)
• Router WAN IP: 10.1.10.254 (RFC1918 private range), gateway 10.1.1.1 — carrier applies CGNAT at BRAS level, no public IPv4 assigned
• DNS: 223.5.5.5 / 223.6.6.6 (Alibaba public DNS, self-configured)

Reproduction:

1. Broadband direct (CGNAT shared exit): immediate #95 Security Violation at launch.
2. Phone hotspot (entirely different carrier, cellular direct): same immediate #95.
3. Via overseas proxy (Clash): game launches, but silently crashes to desktop after a while — no error dialog, no WER crash report, process is terminated.
4. Via UU game accelerator: immediate #95.
5. Router-level game acceleration + proxy: launches, silent crash later.

Local troubleshooting already done (no effect): Secure Boot enabled, no test mode; uninstalled all third-party accelerators (UU/Leigod/KuaiNiao) including kernel drivers and virtual adapters; removed Easy Anti-Cheat leftovers and fully reinstalled EA Javelin (installer verified); disabled all third-party kernel drivers (incl. Tencent ACE-BOOT); verified game file integrity; ran winsock/IP network reset and rebooted. System confirmed clean; unrelated to local software.

Key observations: ① Two independent direct networks (broadband and mobile hotspot) both fail with #95, while an overseas proxy exit works — the issue is not local configuration; ② broadband sits behind carrier CGNAT with a shared exit, whose peak-hour link quality is unstable and may aggravate handshake failure; ③ multiple players report identical EAC/Javelin handshake failures since the Aug 21 update on official EA forums — likely a server-side/route regression for mainland China direct connections to the Javelin handshake service.
