Issie with connecting (WEASEL)
Hello Marathon Support,
I am experiencing a persistent WEASEL error that started suddenly on June 27, 2026. Before that, the game had been working flawlessly since launch.
Issue description
- I can launch the game normally.
- Sometimes I am able to play several matches.
- Eventually, while joining a match, I receive a WEASEL error.
- After the first WEASEL error, I become stuck in a loop:
- "Contacting Marathon Servers..."
- WEASEL
- Return to title screen
- From that point, I cannot log back into the game.
Troubleshooting already completed
Network
- Tested on wired fiber connection (Ethernet).
- Tested on a completely different network using a 5G mobile hotspot.
- Same result on both networks.
Devices
- Windows PC (Steam).
- ASUS ROG Ally X.
- Same issue on both devices.
Steam
- Steam logs in successfully.
- Steam connectivity is normal.
- No authentication errors in Steam logs.
- Steam account is correctly linked to my Bungie account.
BattlEye
- BattlEye starts correctly.
- No BattlEye errors.
- No BattlEye logs indicating failures.
Local files
- Verified game files through Steam.
- Marathon does not generate any crash logs or client logs on my system.
- Only preference files exist in:
AppData\Roaming\Bungie\Marathon\prefs
Bungie account
- I can log into Bungie.net successfully.
- Steam account linkage is present and correct.
Additional information
The problem started suddenly after previously working without issues since launch.
Because the issue occurs:
- on multiple devices,
- on multiple internet connections,
- after successful Steam authentication,
- and specifically during "Contacting Marathon Servers...",
I suspect this may be related to my Marathon account/session on the backend rather than a local network issue.
Could you please check whether my account/session is stuck or whether there are any backend errors associated with it?
