FAQ

Why can't I connect to the server in Once Human?

Usually you're pointed at the wrong region or the login servers are saturated at reset. Pick the exact server/region your character was made on, check maintenance status, and set NAT to Open before retrying.

Can I play Once Human with a friend on a different server?

No — characters are tied to their server/region, so both players must be on the same server to co-op. Create characters on a shared server if you want to play together.

How do I fix Once Human timing out?

Disable any VPN, use a wired connection, confirm you're on the right region, update to the latest patch, and verify game files. Timeouts at reset are usually server-side saturation.
