Login Disconnect

login · 0x00 · clientbound (server → client)

Disconnects the client during login with a text component reason. The server sends it for rejected logins (banned, whitelist, full server, auth failure) and then closes the socket. The client shows the reason on the disconnect screen.

Sent by the server, read by the client. Listen for it with client.on("LoginDisconnect", (data) => …) on the receiving side.

Send it

await client.sendPacket("LoginDisconnect", {
  reason: JSON.stringify({ text: "You are banned.", color: "red" }),
});
client.destroy();

Kicks a client that is still in login. reason is a text component as a JSON string in this state, unlike the NBT Disconnect in config and play.

Field aliases listed under Notes are accepted as alternative keys when writing.
