 - `CLOSED` messages MUST be sent in response to a `REQ` when the relay refuses to fulfill it. It can also be sent when a relay decides to kill a subscription on its side before a client has disconnected or sent a `CLOSE`. This message uses the same pattern of `OK` messages with the machine-readable prefix and human-readable message. Some examples:
   * `["CLOSED", "sub1", "unsupported: filter contains unknown elements"]`
   * `["CLOSED", "sub1", "error: could not connect to the database"]`
   * `["CLOSED", "sub1", "error: shutting down idle subscription"]`
-- The standardized machine-readable prefixes for `OK` and `CLOSED` are: `duplicate`, `pow`, `blocked`, `rate-limited`, `invalid`, and `error` for when none of that fits.
