Once Human error code 409: gear repair fails (fix)
Written by

Trying to repair a weapon or piece of gear fails outright with an "error code 409" message instead of completing the repair.
Also appears as: once human error code 409, once human error 409, repair failed error code 409, repair failes error code 409
This is documented in exactly one Steam Discussions report ("Repair failes error code 409"), which drew replies from other players but no explanation of the cause and no confirmed fix. A 409 in most systems signals a conflict between what the client expects and what the server has on record, which fits a repair action needing to sync inventory state, but that's an inference, not something Once Human has confirmed. Treat this as unconfirmed until a clearer pattern or an official statement shows up.
What to try
- 01Log out and back in, or switch to a different scenario and return, before retrying the repair — a full session refresh has cleared similar sync-style errors for other reported Once Human codes.Unconfirmed
- 02Verify your game files through Steam's Properties menu (Library > Once Human > Properties > Installed Files > Verify integrity of game files), then retry.Unconfirmed
- 03If it persists, report it through the in-game Feedback & Customer Support menu (Esc > Feedback & Customer Support > Bug Report) — Once Human's own support guide names this as the official bug-report channel.Reported
