Error code Goji

Platform: Steam / PC
Region: West South Central
Connection: wired Ethernet

I am repeatedly getting error code GOJI. This error code is not listed in the Marathon error code articles.

Behavior:
- I can launch the game and reach the menu.
- After about 1-2 minutes in the menu, I get kicked with GOJI.
- If I queue into a match, I can sometimes load in, but I get kicked after a few seconds.
- A few times I was able to move/play in short fragments before being kicked again.
- I have also seen YAM occasionally, but GOJI is the main recurring error.
- This has made the game unplayable locally.

Important test:
- The same Steam/Bungie account works on Boosteroid cloud gaming.
- That suggests my account/entitlement is not the issue and the game servers are reachable from another environment.

Troubleshooting already tried:
- Reinstalled Marathon completely through Steam.
- Steam finished a fresh install/build correctly after reinstall.
- Verified/finalized the Steam install.
- Reinstalled/refreshed BattlEye from the Marathon folder.
- Cleared Marathon local prefs/cache.
- Cleared old BattlEye Marathon local cache.
- Restarted Steam and Marathon multiple times.
- Rebooted/restarted networking.
- Tested wired Ethernet.
- Tested T-Mobile mobile hotspot.
- Tested Cloudflare WARP.
- Tested Proton VPN / WireGuard.
- Tested ExitLag.
- Tested Windscribe/WireGuard style routing.
- Disabled VPN/tunnel services and adapters.
- Disabled Cloudflare WARP, Windscribe, Proton, ExitLag, Hamachi, ZeroTier, Radmin, HotspotShield.
- Disabled Wi-Fi and used Ethernet only.
- Removed stale UPnP mappings.
- Allowed Marathon through Windows Firewall.
- Added/confirmed UDP 3074 and 3097 rules/mappings.
- Cleaned old virtual adapter bindings, including VirtualBox bridged networking on Ethernet.
- Checked DNS/proxy/firewall basics.
- Confirmed normal HTTPS connectivity to Bungie/Marathon sites works.

This is not general packet loss or no internet. The game signs in and sometimes loads into a match, then the session gets disconnected by GOJI shortly after.

Please escalate this as a PC/Steam GOJI issue. I need to know what GOJI actually means and what logs or diagnostics you need, because the public troubleshooting guide does not cover this error.
