Room mismatch

Code

AUTH/ROOM_MISMATCH

What it means

The room/realm id asserted by the client does not match what the server stored for this token.

When it happens

• The handshake roomId does not match the stored token record.

Typical scenarios:

• Client tries to reuse a token across different rooms
• Client has a stale realm selection but a token issued for another realm

How to handle

• Treat as authorization failure (403).
• Client should request a new token for the intended realm and reconnect.
