Networkwarning
That identifier is already in use / duplicate license
Also seen as: identifier already in use duplicate license kicked already connected FiveM
What causes it
A player is being rejected because their identifier appears already connected — either a ghost session that didn't clean up, or two clients using the same identifier.
How to fix it
Clear the stale session; ensure players aren't sharing identifiers.
- Wait a moment — a ghost session usually times out and frees the slot.
- Server owners: a deadlock/crash can leave stale sessions; a restart clears them.
- Confirm two people aren't genuinely sharing one account/identifier.
- Check any anti-cheat or connect script isn't wrongly flagging the identifier.
