Severe packet loss issue on Japan server – unplayable experience

Hello,

I’ve been experiencing constant and severe packet loss when playing Apex Legends on the Japan server (Tokyo - GCE 1 and GCE 2). The ping is low (10–20ms) but packets are being dropped every few seconds, making the game unplayable.

I’ve tested multiple things on my side:
- Wired connection via LAN cable
- Restarted router and ONU
- Tried different DNS settings (Google, Cloudflare)
- Ran WinMTR, shows packet loss outside local network
- No VPN used

My ISP (BIGLOBE, Japan) instructed me to contact EA Support, but I couldn’t reach a proper support channel. EA Help redirects me to articles and forums.

Can you please confirm if this is a known issue on the Japan server? Or is there a specific port configuration or regional routing problem that might cause this?

Thanks.
